ΓòÉΓòÉΓòÉ 3. About This Book ΓòÉΓòÉΓòÉ

IBM* Communications Manager/2 Version 1.0 (referred to in this book as
Communications Manager) is a communications services platform. This platform
provides a wide range of services for IBM* Operating System/2* (OS/2*)
workstations that communicate with host computers and with other workstations.
Communications Manager users can choose from among a variety of remote
connectivity options.

This book explains the concepts and procedures for writing Server-Requester
Programming Interface (SRPI) requesters.  A requester is a program that
requests a server to do a task using the SRPI.

Note:  SRPI is designed to be called by 16-bit applications.  It can act as an
       application programming interface between 16-bit applications and either
       16-bit or 32-bit base operating systems.  However, it does not provide
       that interface for 32-bit applications.

This book also explains:

o SRPI
o The SEND_REQUEST function
o Servers
o Routers

The following compilers are supported:

o Microsoft** C 6.0 (referred to as C in the remainder of this book) or its
  functional equivalent

o Micro Focus COBOL/2** (referred to as COBOL in the remainder of this book) or
  its functional equivalent

o IBM Macro Assembler/2* (referred to as MASM in the remainder of this book) or
  its functional equivalent

It is assumed that you are using OS/2 Version 1.30.1 with corrective service
diskette (CSD) 5050 or higher or OS/2 Version 2.0 as your base operating
system. The term OS/2, as it is used in the Communications Manager
documentation and on the display during the running of the programs, refers to
some or all components of the base operating system. If you use a base
operating system that is functionally equivalent to OS/2 Version 1.30.1 with
CSD 5050 or higher or OS/2 Version 2.0, the Communications Manager
documentation still applies.


ΓòÉΓòÉΓòÉ 3.1. Who Should Use This Book ΓòÉΓòÉΓòÉ

This book is intended primarily for application programmers, application
designers, and system designers.  System programmers and IBM technical support
personnel are the secondary audience.

You should be familiar with one or more of the following programming languages:

o C
o COBOL
o Macro Assembler/2


ΓòÉΓòÉΓòÉ 3.2. How to Use This Book ΓòÉΓòÉΓòÉ

The following sections describe the organization of this book and the
conventions used throughout the Communications Manager library.


ΓòÉΓòÉΓòÉ 3.2.1. How This Book Is Organized ΓòÉΓòÉΓòÉ

This book contains the following chapters and appendixes:

SRPI and the SEND_REQUEST Function, describes the functions of the
Server-Requester Programming Interface (SRPI). The SEND_REQUEST parameters
supplied by the requester and the parameters returned from the server in a
SEND_REPLY operation are described. This chapter also provides an overview of
invoking, routing, and linking the SRPI verbs and describes how Communications
Manager applications use SRPI.

C Requesters, discusses the SRPI structure definition, SRPI return codes,
request record initialization, the C send_request function, and linking
subroutines. This chapter provides language-specific notes for C.  It is for
programmers who are writing a requester program in the C language.

COBOL Requesters, discusses SRPI record definitions, SRPI return codes, request
record initialization, the COBOL SENDREQUEST function, and linking subroutines.
This chapter provides language-specific notes for COBOL.  It is for programmers
who are writing a requester program in the COBOL language.

Macro Assembler/2 Requesters, discusses macro definitions, macro parameters,
and the CPRB mapping. This chapter is for programmers who are writing a
requester program in the Macro Assembler/2 language.

Language Binding Routines, provides information to help you decide if a
language binding routine is necessary for your application program.

Migrating Applications from DOS to the OS/2 Environment, describes how to
migrate SRPI/PC application programs from the DOS environment to the IBM OS/2
program environment.

SRPI Return Codes, describes the SRPI return codes for successful and
unsuccessful SEND_REQUEST commands.

Converting the Server Name from ASCII to EBCDIC, provides the table that SRPI
uses for translating the server name from ASCII to EBCDIC.

Connectivity Programming Request Block, describes the physical mapping of the
CPRB.

Product Requirements, describes the product requirements of the IBM personal
computer, IBM Requesters/Servers, Multiple Virtual Storage/Extended
Architecture (MVS/XA*) environment, and Virtual Machine (VM) environment.

An index follows the appendixes. Consult Glossary for definitions of terms used
in this library.  Glossary is available online and is separately orderable.

ΓòÉΓòÉΓòÉ 4.1. Summary of SRPI and ECF Functions ΓòÉΓòÉΓòÉ

The SRPI is a high-level application programming interface (API) that supports
IBM ECF. It also provides a programming interface that allows programmers to
write SRPI requester programs (programs that request servers to perform tasks).
SRPI uses a single verb, SEND_REQUEST, to provide a synchronous call/return
interface to remote server programs.

The IBM System/370 host using IBM ECF provides a method for communicating and
moving functions between different systems.  ECF is a set of programs for
interconnecting IBM personal computers and IBM System/370 host computers
operating with the MVS/XA* or VM/SP environment.

IBM ECF simplifies the way different systems use services over a connection.
ECF provides a single interface that allows application programmers to write
personal computer and host applications that run on a variety of communication
connections.

SRPI has the following characteristics:

o An interface for application programs in a personal computer to request
  services, data, or both from a host.  The requesting program is referred to
  as the SRPI requester.

o An interface for programs in a host to reply to requests for services, data,
  or both from personal computers.  The program that services the request is
  referred to as the server.

The SRPI requester and server programs operate in pairs, with the SRPI
requester in the personal computer and the server in the host computer.

The SRPI router is a Communications Manager facility that uses information
defined in the SRPI server profiles to route SEND_REQUESTs to server programs
using the appropriate 3270 sessions.

See Example of an SRPI Requester and Server for an example of an SRPI requester
and server.

Example of an SRPI Requester and Server


ΓòÉΓòÉΓòÉ 4.2. Using the Server-Requester Programming Interface ΓòÉΓòÉΓòÉ

The API between SRPI requesters from the personal computer and servers on the
host computer is the Server-Requester Programming Interface (SRPI).

Note:  For information about a corresponding interface for servers on the IBM
       host computer, see one of the following publications:

o TSO/E Version 2 Guide to the Server-Requester Programming Interface

o IBM Programmer's Guide to the Server-Requester Programming Interface for
  VM/System Product

When used on a personal computer, SRPI supports only SRPI requesters.  It
provides a call/return function for application-to-application communications.
Using the SEND_REQUEST function, a program on a personal computer calls
(requests) for service from a partner program on a host computer, which returns
(services) the results.

See IBM Personal Computer Requester and IBM Host Computer Server Relationship
for an illustration of the personal computer and host computer relationship.

IBM Personal Computer Requester and IBM Host Computer Server Relationship

Applications use SRPI by issuing the SEND_REQUEST verb. See Issuing a
SEND_REQUEST for further information about this operation.

When a personal computer SRPI requester issues the SEND_REQUEST verb using
SRPI:

 1. The SRPI router converts the request into a structure that the host
    computer router recognizes.

 2. The SRPI router passes the request to the host computer router, using the
    appropriate 3270 terminal emulation session.

 3. The host computer router passes the request to the appropriate host
    computer server.

 4. The host computer server processes the request and passes a reply back to
    the host computer router.

 5. The host computer router passes the reply back to the SRPI router.

 6. The SRPI router converts and returns the reply to the originating SRPI
    requester application. See Example of an SRPI Requester and Server Flow for
    an illustration of the requester and server flow.

ExampleofanSRPIRequesterandServerFlow


ΓòÉΓòÉΓòÉ 4.3. Issuing a SEND_REQUEST ΓòÉΓòÉΓòÉ

You can issue a SEND_REQUEST to the SRPI interface by using one of the
following language support subroutines:

o C
o COBOL
o MASM

You can access the SRPI interface directly without using a provided support
program. See Language Binding Routines, if you do not use a provided support
program to generate the SEND_REQUEST function.


ΓòÉΓòÉΓòÉ 4.4. SEND_REQUEST Parameters ΓòÉΓòÉΓòÉ

The SRPI router sends the request to the host computer using the communications
facilities provided by 3270 terminal emulation. SRPI returns control to the
SRPI requester with an appropriate return code, optional parameters, and
optional data.

The parameters and data associated with the SEND_REQUEST function are described
in Parameters Supplied by the SRPI Requester and in Parameters Returned to the
SRPI Requester.

 2. The server name is used to route the SEND_REQUEST to a 3270 session and to
    invoke the host server.

 3. The address supplied is made up of a selector and an offset. The address
    must give full addressability to the buffer; that is, the sum of the offset
    and the buffer length should not exceed the segment size.

 4. SRPI requesters and servers determine the contents and meaning of the
    application data and parameters pointed to by the addresses in the
    connectivity programming request block (CPRB).


ΓòÉΓòÉΓòÉ 4.5. Routing Your SEND_REQUEST ΓòÉΓòÉΓòÉ

The SRPI requester application invokes a particular server by providing a
server name, which is a parameter supplied in the SEND_REQUEST verb. The server
name matches the name of an SRPI server profile in the active Communications
Manager configuration.

Information defined in the SRPI server profiles is used by the SRPI router to
determine where the server resides. Each server profile associates a server
name with a logical 3270 session.  The 3270 emulator provides access to a
logical 3270 session by way of a logical terminal.  Each logical terminal (LT)
has a name or session ID. When 10 LTs are defined (for example, 10 session
IDs), up to 10 logical 3270 sessions can be active. You can define a total of
twenty-six sessions.

The association of servers with different session IDs makes it possible to
route SEND_REQUESTs to different host sessions.  Note that these host sessions
can be associated with one or more host systems.


ΓòÉΓòÉΓòÉ 4.6. Server Aliases ΓòÉΓòÉΓòÉ

In addition to associating a server with a 3270 session, each SRPI server
profile in a configuration can define an alias for the server. An alias is a
locally known pseudonym for a server. In other words, the alias has meaning
only at the personal computer on which it is defined.  Thus each SRPI server
profile contains three items:

o Server alias
o Server name
o Session ID

The server alias is used chiefly to provide routing flexibility. The SRPI
router uses the server name supplied by the SRPI requester as a key to search
through the list of the SRPI server profiles defined in the active
Communications Manager configuration. The server name supplied by the SRPI
requester is compared with the server alias in each SRPI server profile. If the
server name provided by the SRPI requester matches a server alias defined in an
SRPI server profile, the SEND_REQUEST is routed to the 3270 session defined in
the matching SRPI server profile.  The server name defined in the matched SRPI
server profile is used to invoke the server over the associated 3270 session.

Creating aliases for servers can serve several purposes:

o By using multiple 3270 sessions, you can establish multiple sessions to a
  single host or multiple sessions to more than one host. Multiple sessions
  allow a server (or servers) to be installed on more than one host or to be
  available through more than one session on the same host.

  Multiple sessions may be necessary to allow the same server located at
  different places to have access to different sets of resources, such as
  databases and printers.  An SRPI server profile can be created for each 3270
  session over which the server can be invoked.  Each of these profiles would
  define (for the same server) a different server alias and a different session
  ID.  This allows the SRPI requester application to selectively invoke
  different instances of the same server by using the appropriate server alias
  as the server name on the SEND_REQUEST verb.

o A server alias may be required if two or more different servers have the same
  name.  By assigning an alias to each server, your application can invoke the
  appropriate server by using its server alias.

o A server alias can also be used to give a more meaningful name to a server.

If the name provided by the SRPI requester does not match an alias defined in
an SRPI server profile, the request is returned to the SRPI requester with an
error return code, unless a default route has been configured.


ΓòÉΓòÉΓòÉ 4.7. Using a Default Route ΓòÉΓòÉΓòÉ

It is possible to create an SRPI server profile that does not associate a
specific server name or server alias with a 3270 session ID.  Only one SRPI
server profile of this type can be created for a particular Communications
Manager configuration file. The 3270 session ID associated with this type of
SRPI server profile is the default route.

If the name provided by the SRPI requester application does not match a server
alias in any of the SRPI server profiles defined in the active Communications
Manager configuration file, and a default route is defined, the request is
routed to the 3270 session ID specified as the default route.  If the default
route is selected, the server name supplied by the SRPI requester is used to
invoke the server at the host (using the default 3270 session).

Default routing is particularly useful when:

o All servers are invoked over a single 3270 session.  In such a case, it is
  sufficient to create a single SRPI server profile.  This server profile would
  establish a default route to the 3270 session.

o A majority of the servers are invoked over a single 3270 session. The number
  of SRPI server profiles can be reduced by using a default route to access the
  majority of servers.  Servers accessed over other 3270 sessions require
  additional server profiles.


ΓòÉΓòÉΓòÉ 4.8. Sample SRPI Server Profile Configuration ΓòÉΓòÉΓòÉ

See Sample SRPI Server Profile Configuration for a logical representation of a
sample SRPI configuration.  This figure defines six server profiles. Note that:

o SEND_REQUESTs that specify a server name not defined explicitly as an alias
  in any of the SRPI server profiles are routed through LT2 to a session on
  Host 1.

o SERVER1 can be found on two different host systems.  SERVER1 has two aliases:
  SERVLA and SERVNY.

o SERVER4 does not have an alias, so the real server name is defined as the
  alias.

o MYPRINTR is used to give a more meaningful name to PRT123.

If the SRPI requester application supplies MYPRINTR as the server name, the
SRPI router compares MYPRINTR with the server alias in each SRPI server profile
until a match is found.  In this case, a match is detected, and the
SEND_REQUEST is routed to the server named PRT123 on Host 1 (through LT3).

Additionally, if the requester application supplies SERVER5 as the server name,
the SRPI router will be unable to find an SRPI server profile with a matching
server alias.  In this case, the SEND_REQUEST is routed to the server named
SERVER5 on Host 1 (through LT2).

Note that 3270 sessions not being used for SRPI can be used for other host
applications (for example, PROFS*).

Also note that SRPI routing information derived from the SRPI server profiles
defined in the Communications Manager configuration file is copied into memory
when 3270 Emulation is started. The SRPI router does not actually read the
server profiles each time a SRPI requester issues a SEND_REQUEST. The memory
copy of the routing information is refreshed when 3270 Emulation is stopped and
restarted.

Sample SRPI Server Profile Configuration

Note:  The profile with asterisks in Sample SRPI Server Profile Configuration
       represents the default route. If the server name in the SEND_REQUEST
       connectivity programming request block (CPRB) does not match a server
       alias, the default route is taken. You can create only one server
       profile of this type for a configuration file.

Refer to Configuration Guide for more information regarding the configuration
for 3270 Emulation and SRPI.


ΓòÉΓòÉΓòÉ 4.9. How Communications Manager Applications Use SRPI ΓòÉΓòÉΓòÉ

A local application running on Communications Manager can issue the
SEND_REQUEST verb to an application on a connected remote computer. The local
application is the SRPI requester and the remote application is the intended
server.  The SRPI requester can identify a specific function of the server by
specifying a function ID.

If the contact is successful, the remote application can provide its services
to the SRPI requester.  Information on invoking and implementing the
SEND_REQUEST function follows.

Warning: The base operating system optimizes performance by executing some
subsystems during the processing of the calling application. This exposes some
internal local descriptor table (LDT) selectors to potential misuse by
application programs that have not been fully or correctly debugged.
Accordingly, it is recommended that applications ensure the correct use of LDT
selectors and avoid LDT selector manipulation.


ΓòÉΓòÉΓòÉ 4.10. Invoking SEND_REQUEST ΓòÉΓòÉΓòÉ

When an application invokes SEND_REQUEST, it appears to the program that the
main routine (the local application) calls a subroutine (the remote
application).  The programmer who writes the requester application must perform
the following tasks:

 1. Obtain storage for the connectivity programming request block (CPRB).

 2. Initialize the CPRB.

    This involves setting the default values and completing the application
    parameters.

    Communications Manager provides initialization routines and macros for each
    supported language. These initialization facilities insulate the
    application from the CPRB mapping and call mechanisms.

 3. Call the SRPI dynamic link library (DLL) by issuing SEND_REQUEST.

 4. Validate the SRPI return code received in the CPRB.

The SEND_REQUEST function is implemented as a DLL. For further information see
Linking Your Program.


ΓòÉΓòÉΓòÉ 4.11. Linking Your Program ΓòÉΓòÉΓòÉ

The interface between your application program and the SRPI router is through a
DLL. You create a program module to run on the base operating system (an .EXE
file) by linking your compiled source files using the LINK utility supplied by
the base operating system.

LINK takes the compiled source files, a list of library files, and, optionally,
module definition files that contain information about your program.  From
these files, LINK builds the .EXE file that runs your application program.

If you are developing your application in C or COBOL, input to the linker
includes the appropriate language binding routine:  SRPI_C.OBJ for C language
and SRPI_CBL.OBJ for COBOL.

For further information on the linking process, refer to OS/2 Technical
Library. For specific guidelines about linking Communications Manager APIs, see
Application Programming Guide.


ΓòÉΓòÉΓòÉ 4.12. Concurrent SRPI Requests ΓòÉΓòÉΓòÉ

Multiple applications running on Communications Manager can concurrently issue
the SEND_REQUEST verb. SEND_REQUESTs are serialized by the SRPI router if:

o Two or more SRPI requester applications are concurrently issuing
  SEND_REQUESTs to the same 3270 logical terminal session.

  Since the host computer must serially process requests received over the same
  3270 logical terminal session, SRPI serializes concurrently issued
  SEND_REQUESTs routed to the same 3270 logical terminal session.

  If concurrently issued SEND_REQUESTs are routed to different 3270 logical
  terminal sessions, the host or hosts can process the requests in a concurrent
  fashion.  Requests routed to different 3270 logical terminal sessions are not
  serialized by the SRPI router.

o SEND_REQUESTs are issued concurrently by two or more threads within the same
  application process.

  Concurrent requests issued from multiple threads within an application
  process are always serialized by the SRPI router.

Note:  Serialization of requests is transparent to the application with the
exception of potentially delayed response time.


ΓòÉΓòÉΓòÉ 4.13. Unsolicited 3270 Emulation Screen Updates ΓòÉΓòÉΓòÉ

In order for SEND_REQUESTs to be honored by the host SRPI router (CMSSERV and
MVSSERV), the host SRPI router's logo must be displayed on the 3270 sessions
being used for SRPI.

If the host SRPI router's logo is replaced with other 3270 screen data, the
flow of SRPI data between the SRPI requester and the server may be temporarily
blocked.

When the flow of SRPI data is blocked in this manner, you are notified with a
full screen message, number ACS0123E:

Transmission blocked on session %1.  Switch to this session and
redisplay host ECF logo.%0
You can restore the flow of SRPI data by taking the appropriate action to
refresh the host SRPI router's logo. The message signals you to switch to the
appropriate 3270 session and to take the necessary action to restore the host
SRPI logo.  Operator intervention is usually required to resume the flow of
SRPI data.

The method used to refresh the host SRPI router's logo depends on the host
operating system environment and the reason the host SRPI router's logo was
replaced.  Once the logo is refreshed, the exchange of information between the
SRPI requester and server resumes with no loss of data.

Note that this interaction with the user is transparent to the SRPI requester
application program.  Control returns to the SRPI requester application when
the host SRPI router's logo is refreshed and the server reply is received from
the host computer.

SRPI requesters can be developed that perform one or more of the following
functions using High-Level Language Application Programming Interface (HLLAPI):

o Notify the user that 3270 screen update is blocking transmission of SRPI data

o Capture the contents of 3270 logical display for the user to analyze

o Take appropriate action to restore the host SRPI router's logo (through
  automation or user assistance)

The 3270 screen update notification indicator field in the CPRB allows an SRPI
requester to suppress the notification message.  Suppression is done on a
request basis.

During configuration, you can set the Notification Mode For 3270 Session
parameter to NO, which suppresses the message for all SEND_REQUESTs, regardless
of the setting of the 3270 notification indicator in the CPRB.

The default for C, COBOL, and MASM language support routines does not suppress
the message. An SRPI requester must specify that the message is to be
suppressed.


ΓòÉΓòÉΓòÉ 4.14. SRPI API Trace Facility ΓòÉΓòÉΓòÉ

Communications Manager provides an SRPI API trace that logs the contents of the
CPRB on each call to and return from the SRPI interface.  See Problem
Determination Guide for a complete description of the SRPI API trace.


ΓòÉΓòÉΓòÉ 4.15. Performance Considerations ΓòÉΓòÉΓòÉ

The size of the data transfer buffers used by the SRPI router to exchange data
with the host computer is calculated automatically by Communications Manager.
If your SRPI requester produces requests that transfer large blocks of data to
and from the server, performance may be improved by overriding the data
transfer buffer size calculated by Communications Manager.  This is
accomplished by changing the definition of the logical 3270 display terminals
used for SRPI.

The data transfer buffer-size override parameter supplied on the Create/Change
Logical 3270 Display Terminal window is used to change the buffer size used by
SRPI. A value of 0 indicates that Communications Manager calculates the buffer
size.  Other values (from 1 through 32) specify the buffer size in multiples of
1024 bytes.  Be aware that large values (such as 30) may improve SRPI
performance at the expense of overall system performance. Note that the data
transfer buffer-size override parameter also sets the size of the data transfer
buffers used by the File Transfer feature.


ΓòÉΓòÉΓòÉ 4.16. Handling the Interrupt (Ctrl+Break) Key ΓòÉΓòÉΓòÉ

During processing of a SEND_REQUEST verb, all signals (except numeric
coprocessor signals) are delayed until verb completion. In particular, pressing
the Interrupt (Ctrl+Break) key does not cancel a program during execution of a
SEND_REQUEST verb.


ΓòÉΓòÉΓòÉ 5. C Requesters ΓòÉΓòÉΓòÉ

This chapter is for programmers who want to become familiar with writing a
requester in the C language.

Note:  The Microsoft C Version 6.0 compiler or its functional equivalent is
       referred to as C in this chapter.

This chapter describes:

o C send_request function
o SRPI record definition
o SRPI return codes
o Request record initialization
o Program linking
o Compiler-specific notes

Sample programs are supplied on Communications Manager/2 API Support Diskette,
which is available with Application Programming Guide.

Note:  The function called SEND_REQUEST in other chapters is spelled
       send_request in this chapter to follow C conventions.


ΓòÉΓòÉΓòÉ 5.1. C send_request Function ΓòÉΓòÉΓòÉ

The send_request parameters are grouped into a single C structure of type
UERCPRB.  The init_send_req_parms function is provided to initialize all
send_request parameters in the UERCPRB structure to their defaults.  This
allows the default values to be set once for parameters not used by a
requester.  The send_request function is provided to make synchronous calls to
the server program.

The init_send_req_parms and send_request functions must be linked with your C
application.  Both of these functions are provided in a single object file
(SRPI_C.OBJ) provided with Communications Manager.

The send_request function copies the contents of the UERCPRB structure into a
connectivity programming request block (CPRB) and calls the SRPI DLL. See
Connectivity Programming Request Block, for a description of the CPRB. Once the
server has completed its processing, the send_request procedure copies the
returned parameters from the CPRB into the UERCPRB structure and returns
control to the C application.

CPRB Mapping for the C Application depicts the flow of control between the C
requester, the init_send_req_parms and send_request routines, and the SRPI
router.

CPRB Mapping for the C Application

Note:  The mapping of the CPRB is transparent to the C application. This
       facilitates the portability and migration of applications and insulates
       the applications from dependency on the compiler. Therefore,
       applications should make no assumptions about the mapping of the UERCPRB
       structure to and from the CPRB.

The entry point into the SRPI router DLL is SENDREQ.  The name of the file
containing the SRPI router DLL is SRPI.DLL.  Your C program does not use the
SENDREQ interface directly.  The send_request function (contained within
SRPI_C.OBJ) invoked from your C program uses SENDREQ to call the SRPI router
DLL.

SRPI sends a buffer of parameters, a buffer of data, or buffers containing both
to the server and receives corresponding parameters and data from the server.
SRPI can send any data. A generic type is used for these parameters of the
send_request function.  C uses the type pointer-to-character for these buffer
pointers (for example, char far *my_buffer_pointers).

If the request parameters or data consist of several structures, the
application must convert the data or parameters into a single flat structure
that consists of a contiguous sequence of bytes that are stored in a buffer.
The requesting program must package the request parameters and data in a format
recognizable by the server.

UERCPRB is a packed structure.  That is, each structure member after the first
member is stored at the first available byte.

The memory used for the request parameters can also be used for the reply
parameters; the memory used for the request data can also be used for the reply
data. The application program must ensure that the reply data and parameters
are written into the request data and parameters buffer only when the request
data and parameters are no longer needed.

The object module for the C functions (SRPI_C.OBJ), the declaration files for
the functions, the structure type, and the return codes are provided with
Communications Manager.

The following files are required to develop and run your C application:

UUCCPRB.H This file defines the C record used to issue the send_request
          function. UUCCPRB.H provides definitions for the send_request
          function and the init_send_req_parms procedure.  UUCCPRB.H is needed
          to compile your C program.

SRPI.DLL  This file provides the send_request function.  SENDREQ is the entry
          point into SRPI.DLL.  SRPI.DLL is needed to execute your C program.

SRPI_C.OBJ This is the object file that provides a binding between your C
          program and the SRPI.DLL.  SRPI_C.OBJ is needed to link your C
          program.

ACS.LIB   This is the Communications Manager library file.  ACS.LIB is
          optionally used when linking your C application.  If your program
          definition file does not import SENDREQ, or if you are not using a
          program definition file to link your C application, you should
          specify ACS.LIB when prompted by the linker for library files.


ΓòÉΓòÉΓòÉ 5.2. SRPI Record Definition ΓòÉΓòÉΓòÉ

The UERCPRB record type defines a record passed to the SRPI router using the
send_request function.  The record is defined in an application program by
using the #include preprocessor directive to include the UUCCPRB.H file. See
Supplied Parameters and When a Binding Routine Is Necessary for the definitions
and value ranges of the supplied and returned parameters.

The SRPI record definition follows:

typedef struct {

/* supplied parameters -- not changed by Send_Request */

 char far *uerserver;          /* ASCII name of server address     */
 unsigned short uerfunct;      /* Function ID                      */

/* request parameters and data */

 unsigned short uerqparml;     /* Request parameters length        */
 char far *uerqparmad;         /* Request parameters address       */
 unsigned short uerqdatal;     /* Request data length              */
 char far *uerqdataad;         /* Request data address             */

/* reply parameters and data */

 unsigned short uerrparml;     /* Reply parameters length          */
 char far *uerrparmad;         /* Reply parameters address         */
 unsigned short uerrdatal;     /* Reply data length                */
 char far *uerrdataad;         /* Reply data address               */

/* returned parameters */

 unsigned long uerretcode;     /* Return code                      */
 unsigned long uerservrc;      /* Server return code               */
 unsigned short uerrepldplen;  /* Replied parameters length        */
 unsigned short uerreplddlen;  /* Replied data length              */

/* optional extended function */

 unsigned char uer3270ind      /* 3270 screen update notify        */
                               /* See Note SRPI Record Definition            */
/* reserved field */

 char      uerrsrvd1(149);     /* Reserved field                   */
  } UERCPRB;

#define UER3270NOTIFY 0x00     /* Notify user of 3270 screen update */
#define UER3270DISABL 0xFF     /* Don't notify user of screen update*/

Note:

 1. The pointer in uerserver must point to an 8-byte, left-justified,
    blank-padded (20H) server name.

 2. The supplied parameters are not changed by the send_request function.

 3. All pointers in the UERCPRB structure are 32 bits.

 4. The following returned parameters are undefined unless the SRPI return code
    value returned in uerretcode by the SRPI router is successful:

   o Server return code (uerservrc)
   o Replied parameter length (uerrepldplen)
   o Replied data length (uerreplddlen)

    The SRPI router may or may not have altered these parameters and may or may
    not have set them to 0.  The calling application should not expect these
    parameters to be maintained or altered across any unsuccessful call to the
    SRPI router.

 5. The value returned from the send_request function is identical to the value
    in the uerretcode field in the UERCPRB structure.

 6. If the Notification of 3270 screen update indicator (uer3270ind)  is set to
    X'FF' (UER3270DISABL), the user is not notified when a 3270 screen update
    temporarily blocks transmission of data. The user is notified when the
    Notification of 3270 screen update indicator is set to X'00'
    (UER3270NOTIFY).  All other values are invalid and result in a return code
    of X'0100 0622'.

    The Notification of 3270 screen update indicator (uer3270ind) can be
    overridden by an SRPI configuration option.  If you select No for this
    option, the SRPI feature will not provide notification that a 3270 session
    requires attention because of unsolicited messages, regardless of the value
    specified in uer3270ind.

    A requester can use a 3270 emulation API (such as EHLLAPI) to detect and
    respond to 3270 screen updates.  This requester notifies the user directly
    or handles the situation itself.

    This field defaults to 0 and is initialized to 0 by init_send_req_parms.


ΓòÉΓòÉΓòÉ 5.3. send_request Function Definition ΓòÉΓòÉΓòÉ

To define the send_request function in an application program, use the #include
preprocessor directive to include the UUCCPRB.H file.  Following is the
function declaration:

extern long int send_request (UERCPRB far *);


ΓòÉΓòÉΓòÉ 5.4. SRPI Return Codes ΓòÉΓòÉΓòÉ

To incorporate SRPI return code definitions in an application program, use the
#include preprocessor directive to include the UUCCPRB.H file.

SeeSRPIReturnCodes ,foracompletedescriptionofSRPIreturncodes .


ΓòÉΓòÉΓòÉ 5.5. Request Record Initialization ΓòÉΓòÉΓòÉ

To define the initialization routine in an application program, use the
#include preprocessor directive to include the UUCCPRB.H file.  The
initialization routine sets all parameters that have default values to their
corresponding default values.

The init_send_req_parms function sets all send_request parameters in the
UERCPRB structure that have a default value.  An application program that does
not use all of the send_request parameters can initialize them once and then
ignore them.

The init_send_req_parms function sets default values (all to 0) in the UERCPRB
structure for the following send_request parameters:

o Request parameters pointer
o Request parameters length
o Request data pointer
o Request data length
o Reply parameters buffer pointer
o Reply parameters buffer length
o Reply data buffer pointer
o Reply data buffer length
o Function ID
o Server name (pointer)
o 3270 screen update notification indicator

The init_send_req_parms function initializes the server name pointer to 0.  The
send_request function checks the server name pointer for the value 0.  If the
server name pointer is set to 0, then the CPRB server name is set to blanks
(X'20'). The server name pointer remains set to 0.

The init_send_req_parms function declaration follows:

    extern void pascal far init_send_req_parms(UERCPRB far *);


ΓòÉΓòÉΓòÉ 5.6. Linking Your Program ΓòÉΓòÉΓòÉ

The C send_request function and init_send_req_parms function are implemented as
entry points into an object file (SRPI_C.OBJ) provided for C programmers.

Note:  The object module used when linking your C application program is
       SRPI_C.OBJ. SRPI.DLL is the SRPI router dynamic link library that is
       called by the send_request function.

When linking your C application program, include SRPI_C.OBJ in the list of
object modules passed to the linker.

The C application must provide at least 2560 bytes of stack when calling the
SRPI_C.OBJ module.  Ensure that your application program stack is large enough
to meet this requirement.

To implement load-time dynamic linking to the SRPI SENDREQ function provided by
the SRPI router, use the following:

o The entry points into the C language support routines.  These are used in
  your C source code:

   - send_request
   - init_send_req_parms

o The entry point into the SRPI router dynamic link library is SENDREQ. This
  entry point should be imported in the program definition file for your C
  application. See Communications Manager/2 API Support Diskette for more
  information. This diskette is available with Application Programming Guide.

o The import library file name is ACS.LIB. This is optional input to the linker
  and is necessary only if you do not import SENDREQ in your link definition
  file.

Run-time dynamic linking is not supported by the send_request function provided
with the SRPI_C.OBJ module.


ΓòÉΓòÉΓòÉ 6. COBOL Requesters ΓòÉΓòÉΓòÉ

This chapter is for programmers who want to become familiar with writing an
SRPI requester in the COBOL language.

Note:  The Micro Focus COBOL/2 compiler (or its functional equivalent) is
       referred to as COBOL in this chapter.

This chapter describes:

o COBOL SENDREQUEST function
o SRPI record definition
o SRPI return codes
o Request record initialization
o Program linking
o Compiler-specific notes

Sample programs are supplied on Communications Manager/2 API Support Diskette,
which is available with Application Programming Guide.

Note:  The function called SEND_REQUEST in other chapters is spelled
       SENDREQUEST in this chapter to follow COBOL conventions.


ΓòÉΓòÉΓòÉ 6.1. COBOL SENDREQUEST Function ΓòÉΓòÉΓòÉ

The SENDREQUEST parameters are grouped into a single COBOL structure of type
UERCPRB.  The INIT_SEND_REQ_PARMS function is provided to initialize all
SENDREQUEST parameters in the UERCPRB structure to their defaults.  This allows
the default values to be set once for parameters not used by an SRPI requester.
The SENDREQUEST function is provided to make synchronous calls to the server
program.

The INIT_SEND_REQ_PARMS and SENDREQUEST functions must be linked with your
COBOL application.  Both of these functions are provided in a single object
file (SRPI_CBL.OBJ) provided with Communications Manager.

The SENDREQUEST function copies the contents of the UERCPRB structure into a
CPRB (see Connectivity Programming Request Block) and calls the SRPI dynamic
link library. Once the server has completed its processing, the SENDREQUEST
function copies the returned parameters from the CPRB into the UERCPRB
structure and returns control to the COBOL application.

CPRB Mapping for the COBOL Application depicts the flow of control between the
COBOL requester, the INIT_SEND_REQ_PARMS and SENDREQUEST routines, and the SRPI
router.

CPRB Mapping for the COBOL Application

Note:  The mapping of the CPRB is transparent to the COBOL application. This
       facilitates the portability and migration of applications, and insulates
       the applications from dependency on the compiler. Therefore,
       applications should make no assumptions about the mapping of the UERCPRB
       structure to and from the CPRB.

The entry point into the SRPI router dynamic link library is SENDREQ.  The name
of the file containing the SRPI router dynamic link library is SRPI.DLL. Your
COBOL program does not use the SENDREQ interface directly. The SENDREQUEST
function (contained within SRPI_CBL.OBJ) invoked from your COBOL program uses
SENDREQ to call the SRPI router dynamic link library.

SRPI sends a buffer of parameters, a buffer of data, or buffers containing both
to the server and receives corresponding parameters and data from the server.
SRPI can send any data. A generic type is used for these parameters of the
SENDREQUEST function.

If the request parameters or data consist of several structures, the
application must convert the data or parameters into a single flat structure
that consists of a contiguous sequence of bytes that are stored in a buffer.
The requesting program must package the request parameters and data in a format
recognizable by the server.

The memory used for the request parameters can also be used for the reply
parameters; the memory used for the request data can also be used for the reply
data. The application program must ensure that the reply data and parameters
are written into the request data and parameters buffer only when the request
data and parameters are no longer needed.

The object module for the COBOL functions (SRPI_CBL.OBJ), the declaration files
for the functions, the structure type, and the return codes are provided with
Communications Manager.

The following files are required to develop and run your COBOL application:

UUBCPRB.CBL This file defines the COBOL record used to issue the SENDREQUEST
          function. UUBCPRB.CBL is needed to compile your COBOL program.

SRPI.DLL  This is the SRPI dynamic link library that provides the SENDREQ
          function.  SENDREQ is the entry point into SRPI.DLL.  SRPI.DLL is
          needed to execute your COBOL program.

SRPI_CBL.OBJ This is the object file that provides a binding between your COBOL
          program and the SRPI dynamic link library (SRPI.DLL). SRPI_CBL.OBJ is
          needed to link your COBOL program.

ACS.LIB   This is the Communications Manager library file.  ACS.LIB is
          optionally used when you link your COBOL application.  If your
          program definition file does not import SENDREQ, or if you are not
          using a program definition file to link your COBOL application, you
          should specify ACS.LIB when prompted by the linker for library files.


ΓòÉΓòÉΓòÉ 6.2. SRPI Record Definition ΓòÉΓòÉΓòÉ

The UERCPRB structure defines a record passed to the SRPI router using the
SENDREQUEST function. To define the record in an application program, use the
COPY statement to include the UUBCPRB.CBL file. See Supplied Parameters and
When a Binding Routine Is Necessary for the definitions and value ranges of the
supplied and returned parameters.

The SRPI record definition follows:

  01 UERCPRB

***  SUPPLIED PARAMETERS -- NOT CHANGED BY SENDREQUEST  ***

     03  UERSERVER            PIC X(8).  /* ASCII name of server address */

     03  UERSERVRC            PIC 9(9)  COMP-5.  /* Server return code   */
     03  UERREPLDPLEN         PIC 9(4)  COMP-5.  /* Replied parameters   */
                                                 /* length               */
     03  UERREPLDDLEN         PIC 9(4)  COMP-5.  /* Replied data length  */

     03  UERRSVD1             PIC X(149).        /* Reserved field       */

***  CONSTANTS FOR INITIALIZING UER3270IND               ***

  88  UER3270NOTIFY   VALUE IS ZERO.             /* Notify user of 3270  */
                                                 /* screen update        */
  88  UER3270DISABL   VALUE IS 255.              /* Do not notify user   */
                                                 /* of screen update     */

Note:

 1. The name in the server field (UERSERVER) must be left-justified and padded
    with blanks.

 2. The supplied parameters are not changed by the SENDREQUEST function.

 3. When the return code value returned in UERRETCODE by the SRPI router is not
    successful, the following returned parameters are undefined:

   o Server return code (UERSERVRC)
   o Replied parameter length (UERREPLDPLEN)
   o Replied data length (UERREPLDDLEN)

    The SRPI router may or may not have altered these parameters and may or may
    not have initialized these parameters to 0. The calling application should
    not expect these fields to be maintained or altered across any unsuccessful
    call to the SRPI router.

 4. The value returned from the SENDREQUEST function is identical to the value
    in the ERRETCODE field in the UERCPRB structure.

 5. If the Notification of 3270 screen update indicator (uer3270ind)  is set to
    X'FF' (UER3270DISABL), the user is not notified when a 3270 screen update
    temporarily blocks transmission of data. The user is notified when the
    Notification of 3270 screen update indicator is set to X'00'
    (UER3270NOTIFY).  All other values are invalid and result in a return code
    of X'0100 0622'.

    The Notification of 3270 screen update indicator (uer3270ind) can be
    overridden by an SRPI configuration option.  If you select No for this
    option, the SRPI feature will not provide notification that a 3270 session
    requires attention because of unsolicited messages, regardless of the value
    specified in uer3270ind.

    A requester can use a 3270 emulation API (such as EHLLAPI) to detect and
    respond to 3270 screen updates.  This requester notifies the user directly
    or handles the situation itself.

    This field defaults to 0 and is initialized to 0 by init_send_req_parms.


ΓòÉΓòÉΓòÉ 6.3. SRPI Return Codes ΓòÉΓòÉΓòÉ

To incorporate SRPI return code definitions in an application program, use the
COPY command to include the UUBCPRB.CBL file.

SeeSRPIReturnCodes ,foracompletedescriptionofSRPIreturncodes .


ΓòÉΓòÉΓòÉ 6.4. Request Record Initialization ΓòÉΓòÉΓòÉ

To define the initialization routine in an application program, use the COPY
command to include the UUBCPRB.CBL file.  The initialization routine sets all
parameters that have default values to their corresponding default values.

The INIT_SEND_REQ_PARMS function sets all SENDREQUEST parameters in the UERCPRB
structure that have a default value.  An application program that does not use
all of the SENDREQUEST parameters can initialize them once and then ignore
them.

The INIT_SEND_REQ_PARMS function sets default values (all to 0) in the UERCPRB
structure for the following SENDREQUEST parameters:

o Request parameters pointer
o Request parameters length
o Request data pointer
o Request data length
o Reply parameters buffer pointer
o Reply parameters buffer length
o Reply data buffer pointer
o Reply data buffer length
o Function ID
o Server name
o 3270 screen update notification indicator

The INIT_SEND_REQ_PARMS function initializes the server name to blanks.


ΓòÉΓòÉΓòÉ 6.5. Linking Your Program ΓòÉΓòÉΓòÉ

The COBOL SENDREQUEST function and INIT_SEND_REQ_PARMS function are implemented
as entry points into an object file (SRPI_CBL.OBJ) provided for COBOL
programmers.

Note:  The object module used when linking your COBOL application program is
       SRPI_CBL.OBJ. SRPI.DLL is the SRPI router dynamic link library that is
       called by the SENDREQUEST function.

When linking your COBOL application program, include SRPI_CBL.OBJ in the list
of object modules passed to the linker.

The COBOL application must provide at least 2560 bytes of stack when you call
the SRPI_CBL.OBJ module. Ensure that your application program stack is large
enough to meet this requirement.

To implement load-time dynamic linking to the SRPI SENDREQ function provided by
the SRPI router, use the following:

o The entry points into the COBOL language support routines.  These are used in
  your COBOL source code:

   - SENDREQUEST
   - INIT_SEND_REQ_PARMS

o The entry point into the SRPI router dynamic link library is SENDREQ. This
  entry point should be imported in the program definition file for your COBOL
  application. See the Communications Manager/2 API Support Diskette diskette
  for more information. This diskette is included with Application Programming
  Guide.

o The import library file name is ACS.LIB. This is optional input to the linker
  and is necessary only if you do not import SENDREQ in your link definition
  file.

Run-time dynamic linking is not supported by the SENDREQUEST function provided
with the SRPI_CBL.OBJ module.


ΓòÉΓòÉΓòÉ 7. Macro Assembler/2 Requesters ΓòÉΓòÉΓòÉ

This chapter is for programmers who want to become familiar with writing an
SRPI requester in the Macro Assembler/2 language.

Note:  The Macro Assembler/2 compiler or its functional equivalent is referred
       to as MASM in this chapter.

This chapter describes:

o Macro definitions
o SRPI return codes
o Macro parameters
o Connectivity programming request block (CPRB) mapping
o Program linking

Sample programs are supplied on Communications Manager/2 API Support Diskette,
which is available with Application Programming Guide.


ΓòÉΓòÉΓòÉ 7.1. Macro Definitions ΓòÉΓòÉΓòÉ

Macro definitions perform the following tasks:

o Provide CPRB mapping
o Initialize the CPRB with default values
o Set the required parameters in the CPRB
o Set the request buffers parameters, which are optional, in the CPRB
o Set the reply buffers parameters, which are optional, in the CPRB
o Set the Notification of 3270 screen update indicator
o Call the SRPI dynamic link library
o Move the returned fields from the CPRB to user-defined data fields

The following files are required to develop and run your MASM application:

UUMCPRB.INC This file defines the MASM UERCPRB structure definition used to
          issue the SENDREQUEST function. UUMCPRB.INC is needed to compile your
          MASM program.

SRPI.DLL  This file provides the SENDREQ function.  SENDREQ is the entry point
          into SRPI.DLL.  SRPI.DLL is needed to execute your MASM program.

UUMINFAC.MAC This file contains the interface macros used to build the UERCPRB
          structure and access the SRPI.DLL file. UUMINFAC.MAC is needed to
          assemble your MASM program.

ACS.LIB   This is the Communications Manager library file.  ACS.LIB is
          optionally used when you link your MASM application.  If your program
          definition file does not import SENDREQ, or if you are not using a
          program definition file to link your MASM application, you should
          specify ACS.LIB when prompted by the linker for library files.

During assembly, the INCLUDE command contained in MASM includes the SRPI router
macros.  The files to be included are:

o UUMCPRB.INC, which is the UERCPRB structure definition

o UUMINFAC.MAC, which includes the interface macros used during assembly

The application program provides storage for the CPRB.  The UUMCPRB file
defines the required size of the CPRB. See Connectivity Programming Request
Block, for a description of the CPRB.

Invoking the macros does not cause changes to registers, except for the
SEND_REQUEST macro that modifies the AX and BX registers.  To maintain register
contents, the application program must have a valid stack pointer in the SS:SP
registers.  The stack pointer is required because the instructions, which the
macros generate, push register values onto the stack prior to altering a
register's contents.

At least 2560 bytes of stack should be available when using the SRPI macros.
Ensure that your application stack is large enough to meet this requirement.

See Supplied Parameters and When a Binding Routine Is Necessary for the
semantics and value ranges of the supplied and returned parameters.


ΓòÉΓòÉΓòÉ 7.2. SRPI Return Codes ΓòÉΓòÉΓòÉ

You can include SRPI return code definitions in an application program by using
the INCLUDE command to include the UUMCPRB.INC file.

SeeSRPIReturnCodes ,foracompletedescriptionofSRPIreturncodes .


ΓòÉΓòÉΓòÉ 7.3. Macro Parameters ΓòÉΓòÉΓòÉ

The ES:DI registers must point to the CPRB whenever any of the macros are
invoked.  Several of the parameters are specified as locations. A location
indicates that the actual parameter should be a variable name or register
designation giving a memory location, using MASM syntax.  The offset register
designation may be [BX] or one of the index registers [SI] or [DI].  It is
assumed that DS is the data segment register.  To override this assumption, use
the ES: segment override prefix.

The following examples are valid location parameters:

o My_variable_name
o My_variable_name [BX]
o My_variable_name [SI]
o My_variable_name [BX] [DI]
o ES:My_variable_name
o ES:My_variable_name [BX]

Vectors are doubleword address fields containing an offset followed by a
selector, with the bytes within a word reversed.  Vectors are used where the
parameter is a pointer (for example, to a buffer or to the CPRB).

The macros can be invoked with null parameters.  When a parameter is null, the
corresponding field in the CPRB is not accessed.  All parameters are optional
in terms of invoking macros.  The SRPI requester application should not issue
the SEND_REQUEST verb until all fields in the CPRB have been set to their
intended values; for example:

    SET_REPLY_BUFFERS ,,mdabuf@,mdabufl


ΓòÉΓòÉΓòÉ 7.3.1. SEND_REQ_INIT Macro ΓòÉΓòÉΓòÉ

The SEND_REQ_INIT macro sets default values to 0 (except server name, which
defaults to blanks) in the CPRB for the following SEND_REQUEST parameters:

o Request parameters pointer
o Request parameters length
o Request data pointer
o Request data length
o Reply parameters buffer pointer
o Reply parameters buffer length
o Reply data buffer pointer
o Reply data buffer length
o Function ID
o Server name
o Unsolicited message indicator

The SEND_REQ_INIT macro syntax is as follows:

    SEND_REQ_INIT


ΓòÉΓòÉΓòÉ 7.3.2. SET_REQ_PARMS Macro ΓòÉΓòÉΓòÉ

The SET_REQ_PARMS macro sets all the SEND_REQUEST parameters except the request
and reply buffer information.  The SET_REQ_PARMS macro syntax follows:

    SET_REQ_PARMS  SERV_NAM,FUNCT

SERV_NAM
          The location of the server name, which is assumed to be 8 bytes in
          length, left-justified and padded with blanks.  The SERV_NAM value
          must be reachable from the DS register and indicated in one of the
          following ways:

   o The character string: DSSI.

     The DS:SI register pair points to the left character of the server name to
     be moved into the CPRB.

   o Any valid source operand for the LEA SI,source instruction.

FUNCT
          The location of a word containing the function ID value, a literal
          value, or a label equated to the function ID.  The location is
          indicated in one of the following ways:

   o The character string: AX.

     The AX register contains the function ID to be moved into the CPRB.

   o Any valid source operand for the MOV AX,source instruction.


ΓòÉΓòÉΓòÉ 7.3.3. SET_REQ_BUFFERS Macro ΓòÉΓòÉΓòÉ

The SET_REQ_BUFFERS macro sets the values of the request data and request
parameters buffers and the corresponding lengths.  The SET_REQ_BUFFERS macro
syntax follows:

    SET_REQ_BUFFERS QPARM_BUF,QPARM_LEN,QDATA_BUF,QDATA_LEN

QPARM_BUF
          The location of a vector that points to the request parameter buffer;
          must be specified so as to be a valid substitution for the source
          operand in the MOV AX,source and MOV AX,source + 2 instructions.

QPARM_LEN
          The location of a word that contains the length of the request
          parameters buffer or a label equated to the length.  The length is
          indicated in one of the following ways:

   o The character string: CX.

     The CX register contains the length to be moved into the CPRB.

   o Any valid source operand for the MOV AX, source instruction.

QDATA_BUF
          The location of a vector that points to the request buffer; must be
          specified so as to be a valid substitution for the source operand in
          the MOV AX,source and MOV AX,source + 2 instructions.

QDATA_LEN
          The location of a word that contains the length of the request data
          buffer or a label equated to the length. This is indicated in one of
          the following ways:

   o The character string: DX.

     The DX register contains the length to be moved into the CPRB.

   o Any valid source operand for the MOV DX,source instruction.


ΓòÉΓòÉΓòÉ 7.3.4. SET_REPLY_BUFFERS Macro ΓòÉΓòÉΓòÉ

The SET_REPLY_BUFFERS macro sets the value of the reply data and reply
parameters buffers and the corresponding pointers.  The SET_REPLY_BUFFERS macro
syntax follows:

    SET_REPLY_BUFFERS PARM_BUF,PARM_LEN,DATA_BUF,DATA_LEN

PARM_BUF
          The location of the vector that points to the reply parameters
          buffer; must be specified so as to be a valid substitution for the
          source operand in the MOV AX,source and MOV AX,source + 2
          instructions.

PARM_LEN
          The location of a word that contains the length of the reply
          parameters buffer or a label equated to the length.  The location is
          indicated in one of the following ways:

   o The character string: CX.

     The CX register contains the length to be moved into the CPRB.

   o Any valid source operand for the MOV CX,source instruction.

DATA_BUF
          The location of the vector that points to the reply data buffer; must
          be specified so as to be a valid substitution for the source operand
          in the MOV AX,source and MOV AX,source + 2 instructions.

DATA_LEN
          The location of a word that contains the length of the reply data
          buffer or a label equated to the length. This is indicated in one of
          the following ways:

   o The character string: DX.

     The DX register contains the length to be moved into the CPRB.

   o Any valid source operand for the MOV DX,source instruction.


ΓòÉΓòÉΓòÉ 7.3.5. SET_3270_NOTIFY_ON Macro ΓòÉΓòÉΓòÉ

The SET_3270_NOTIFY_ON macro sets the Notification of 3270 screen update
indicator to X'00' in the CPRB.  This is the default setting.  The
SEND_REQ_INIT macro also sets this indicator to X'00'. The SET_3270_NOTIFY_ON
macro syntax follows:

    SET_3270_NOTIFY_ON


ES : DImustcontaintheselectorandoffsetoftheCPRBwhenthismacroisinvoked .


ΓòÉΓòÉΓòÉ 7.3.6. SET_3270_NOTIFY_OFF Macro ΓòÉΓòÉΓòÉ

The SET_3270_NOTIFY_OFF macro sets the Notification of 3270 screen update
indicator to X'FF' in the CPRB. You should use this macro only if the SRPI
requester program is designed to handle 3270 screen updates. The
SET_3270_NOTIFY_OFF macro syntax follows:

    SET_3270_NOTIFY_OFF


ES : DImustcontaintheselectorandoffsetoftheCPRBwhenthismacroisinvoked .


ΓòÉΓòÉΓòÉ 7.3.7. SEND_REQUEST Macro ΓòÉΓòÉΓòÉ

The SEND_REQUEST macro executes the SEND_REQUEST verb by calling the SRPI
dynamic link library (SRPI.DLL). The SEND_REQUEST macro syntax follows:

    SEND_REQUEST


ES : DImustcontaintheselectorandoffsetoftheCPRBwhenthismacroisinvoked .

The direction flag is cleared upon return from the code generated by the
SEND_REQUEST macro.

When the SRPI router processes a request successfully, the AX register is set
to 0 upon return to the calling application.  If the AX register is not 0, the
SRPI router is not loaded and the request is not processed.

Note:  Applications that use the SEND_REQUEST macro to invoke the SRPI router
       do not have to examine the contents of the AX register to determine if
       the SRPI router is loaded. The instructions expanded by the SEND_REQUEST
       macro move the appropriate value into the return code field in the CPRB
       when the SRPI router is not loaded.


ΓòÉΓòÉΓòÉ 7.3.8. GET_REPLY Macro ΓòÉΓòÉΓòÉ

After you issue a SEND_REQUEST, the GET_REPLY macro retrieves the return
parameters.  The GET_REPLY syntax follows:

    GET_REPLY RET_CODE,SERV_RC,REP_PARM_LEN,REP_DATA_LEN

RET_CODE
          Location of a doubleword to which the return code should be moved;
          must be specified so as to be a valid substitution for the target
          operand in the MOV target,CX and MOV target + 2,CX instructions.

SERV_RC
          Location of a doubleword to which the server return code should be
          moved; must be specified so as to be a valid substitution for the
          target operand in the MOV target,CX and MOV target + 2,CX
          instructions.

REP_PARM_LEN
          The CPRB replied parameters length is moved to this location of a
          word.  This is indicated in one of the following ways:

   o The character string: BX.

     The field is moved into register BX.

   o Any valid target operand for the MOV target,CX instruction.

REP_DATA_LEN
          The CPRB replied data length is moved to this location of a word.
          This is indicated in one of the following ways:

   o The character string: CX.

     The field is moved into the CX register.

   o Any valid target operand for the MOV target,CX instruction.


ΓòÉΓòÉΓòÉ 7.4. CPRB Mapping ΓòÉΓòÉΓòÉ

A pseudo-op called the MASM STRUC is used to define the CPRB. To define the
CPRB in an application program, use the INCLUDE pseudo-op to include the
UUMCPRB.INC file.  The following is the CPRB structure definition:

uercprb       STRUC
uerrbsiz       dw            ?        ;Size of CPRB in bytes
uerversion     dw            ?        ;Version number
uerretcode     dd            ?        ;Return code

The UUMCPRB file does not allocate memory for the CPRB.  The SRPI requester
program allocates memory for the CPRB by using the define byte.  An example of
the define byte follows:

uumcprbseg     SEGMENT  'data'
uumcprb        db       SIZE uercprb dup  (OFFH)  ;Allocate space
;                                                  for CPRB
uumcprbseg     ENDS

Note:

 1. The following CPRB returned parameters are undefined unless the SRPI return
    code value returned in uerretcode by the SRPI router is successful:

   o Server return code (uerservrc)
   o Replied parameter length (uerrepldplen)
   o Replied data length (uerreplddlen)

 2. The SRPI router may or may not have altered these parameters and may or may
    not have initialized these parameters to 0.  The calling application should
    not expect these parameters to be maintained or altered across any
    unsuccessful call to the SRPI router.

 3. If the Notification of 3270 screen update indicator (uer3270ind)  is set to
    X'FF' (UER3270DISABL), the user is not notified when a 3270 screen update
    temporarily blocks transmission of data. The user is notified when the
    Notification of 3270 screen update indicator is set to X'00'
    (UER3270NOTIFY).  All other values are invalid and result in a return code
    of X'0100 0622'.

    The Notification of 3270 screen update indicator (uer3270ind) can be
    overridden by an SRPI configuration option.  If you select No for this
    option, the SRPI feature will not provide notification that a 3270 session
    requires attention because of unsolicited messages, regardless of the value
    specified in uer3270ind.

    A requester can use a 3270 emulation API (such as EHLLAPI) to detect and
    respond to 3270 screen updates.  This requester notifies the user directly
    or handles the situation itself.

    This field defaults to 0 and is initialized to 0 by init_send_req_parms.


ΓòÉΓòÉΓòÉ 8. Language Binding Routines ΓòÉΓòÉΓòÉ

This chapter assists application programmers who plan to utilize SRPI in the
OS/2* environment when using programming languages other than C, COBOL, or
Macro Assembler/2.

Note:

 1. The Microsoft C Version 6.0 compiler (or its functional equivalent) is
    referred to as C in this chapter.

 2. The Micro Focus COBOL/2 compiler (or its functional equivalent) is referred
    to as COBOL in this chapter.

 3. The Macro Assembler/2 compiler (or its functional equivalent) is referred
    to as MASM in this chapter.

The following sections help the application programmer determine whether a
language binding routine is necessary.

A language binding routine provides an interface between an application program
and the SRPI (as defined at the assembler level).


ΓòÉΓòÉΓòÉ 8.1. When a Binding Routine is Not Necessary ΓòÉΓòÉΓòÉ

If you can perform the following steps with your chosen language, a language
binding routine is not necessary:

 1. Allocate and map the connectivity programming control block (CPRB). See
    Connectivity Programming Request Block, for the layout of the CPRB.

 2. Initialize the CPRB.  The following initialization steps should be
    completed once before calling SRPI:

   o Initialize the entire CPRB to 0
   o Set the CPRB length field to X'0068' (stored byte-reversed)
   o Set the CPRB version number to X'0200' (stored byte-reversed)
   o Set the verb type to X'01'
   o Set the server name length to X'08'

 3. Before each call to SRPI, set up the application-specific information:

   o Function ID
   o Request parameters length
   o Address of parameters
   o Request data length
   o Address of data
   o Reply parameters buffer length
   o Address of reply parameters
   o Reply data buffer length
   o Address of reply data
   o Server name (ASCII)
   o Unsolicited message indicator

 4. Perform a far call to the SRPI dynamic link library with the 32-bit address
    of the CPRB pushed onto the stack prior to the call. The entry point into
    the SRPI dynamic link library is SENDREQ.

 5. Upon return from the SRPI call, the CPRB address is removed from the stack
    and AX is set to X'0000' if the SRPI function is present and loaded.  If
    the SRPI dynamic link library is present but the SRPI feature is not loaded
    as a feature of Communications Manager, AX is returned as X'0103'. With the
    exception of AX and SP, all other registers are preserved. Note, however,
    that the direction flag is cleared.

 6. Examine the SRPI return code.  If the SRPI return code is 0, examine the
    server return code.  If the server return code is successful, examine the
    replied parameter length field and the replied data length field to
    determine the parameters and data returned from the server.


ΓòÉΓòÉΓòÉ 8.2. When a Binding Routine Is Necessary ΓòÉΓòÉΓòÉ

If you cannot perform any of the preceding tasks, a binding routine may be
required. For example, if you cannot allocate and map contiguous storage for
the CPRB, or if the calling convention for your language requires that AX be
preserved across the call, a binding routine is required.

A binding routine is required if the calling convention for your language
requires that the called procedure does not remove parameters from the stack.

The language binding routine that you write must handle the following tasks in
the following order:

 1. Handle the calling and parameter-passing conventions associated with the
    application language

 2. Initialize the CPRB as appropriate

 3. Map the parameters passed from the application into the CPRB format

 4. Perform the dynamic link call to SRPI

 5. Set up the return parameters for the application

 6. Handle the conventions associated with returning control and parameters
    back to the application

If you use a language that allows you to code the language binding routine in
MASM, you can perform steps When a Binding Routine Is Necessary through When a
Binding Routine Is Necessary with the following macros:

o SEND_REQ_INIT
o SET_REQ_PARMS
o SET_REQ_BUFFERS
o SET_REPLY_BUFFERS
o SEND_REQUEST
o GET_REPLY

Steps When a Binding Routine Is Necessary and When a Binding Routine Is
Necessary are language-specific and must be handled by the language binding
routine.


ΓòÉΓòÉΓòÉ 9. Migrating Applications from DOS to the OS/2 Environment ΓòÉΓòÉΓòÉ

This chapter assists application programmers who want to convert application
programs (which use SRPI) from the DOS environment to the OS/2 environment.  It
describes the major differences between the programming interface provided by
SRPI in DOS products and the one provided by SRPI in OS/2 products.

For a detailed description of the interface to SRPI for DOS products, see
Programmer's Guide to the Server-Requester Programming Interface for the
Personal Computer and the IBM 3270-PC.

In order to run an SRPI application program that was written for DOS in the
OS/2 environment, few changes are necessary with respect to the SRPI interface.
If the application was written in C or Macro Assembler/2 (MASM) and the
language support routines provided by IBM were used, it should be sufficient to
recompile and relink the application program after you have appropriately
modified any operating system interfaces.

If the application program does not take advantage of the language support
facilities, minor coding changes may be required.  In addition, if the
application recognizes specific nonzero SRPI return codes, it may be necessary
to add code to recognize new SRPI return codes.  If the application does not
discriminate between the various unsuccessful SRPI return codes, no change is
required.

The changes can be grouped into the following categories:

o Interface to SRPI
o Verb structure
o Return codes


ΓòÉΓòÉΓòÉ 9.1. Interface to SRPI ΓòÉΓòÉΓòÉ

Requests for the SEND_REQUEST service have been changed from:

interrupt X'7F' with ES:DI pointing to the CPRB
to:

CALL SENDREQ with the 32-bit address of the CPRB pushed onto the stack prior to
the call.

Note:  These details are hidden from the application if the language support
       facilities were used.

Also, the DOS interface requires the program to set AX to X'0103'  prior to
invoking interrupt X'7F'.  If the SRPI function is loaded, AX is reset to 0. To
preserve compatibility, the OS/2 version of SRPI returns AX set to X'0103' if
SRPI has not been loaded, and it returns AX set to 0 if SRPI is loaded.

It is not necessary for an application written for the OS/2 version of SRPI to
either set AX prior to the call or to examine it after the call.  It is
sufficient to examine the return code set in the CPRB.


ΓòÉΓòÉΓòÉ 9.2. Verb Structure ΓòÉΓòÉΓòÉ

The CPRB has been changed.  The version ID must be X'0200' and the Notification
of 3270 screen update indicator flag must be set to X'FF' or X'00'.

A reserved field has been added at the end of the CPRB structures provided for
both C and COBOL. The CPRB structures for C are found in UUCCPRB.H. The CPRB
structures for COBOL are found in UUBCPRB.CBL and UUPCPRB.INC. The reserved
field is used by the base operating system and should not be used by the
application. No code changes are required to accommodate this reserved field.


ΓòÉΓòÉΓòÉ 9.3. New Return Codes ΓòÉΓòÉΓòÉ

The following return codes are not generated by SRPI in the OS/2 environment:

o SRPI router busy
o TopView* not supported

It is not required that references to these return codes be removed from the
application program, since the return code definitions for these two return
codes remain in the language support files.

The following return codes are new to the OS/2 environment:

o Undefined server name (routing error)
o 3270 emulation reinitialized since last use
o 3270 session in use by File Transfer (IND$FILE)
o Communications resource not available
o Invalid CPRB segment
o Notification of 3270 screen update indicator not valid


ΓòÉΓòÉΓòÉ 9.4. Data Sharing ΓòÉΓòÉΓòÉ

The CPRB and the parameter and data buffers must be in read/write storage.
This storage can be shared or non-shared.  Storage can be allocated in a static
manner within the program or dynamically.  No code changes are necessary if
these requirements are met.


ΓòÉΓòÉΓòÉ 9.5. Design Suggestions ΓòÉΓòÉΓòÉ

The programmer is encouraged to use the C or COBOL high-level languages or to
use the interface macros if the application is written in the MASM language.

o By using the C or COBOL high-level language, the programmer can take
  advantage of the language binding routines.  If the language chosen is MASM,
  the programmer is encouraged to use the interface macros.

o By using the C, COBOL, or MASM interface macros, the programmer can isolate
  the application program from changes to the SRPI interface.

If the language chosen is not supported by the OS/2 base operating system, the
programmer may need a language binding routine tailored to the OS/2
environment.  See Language Binding Routines, for further information.


ΓòÉΓòÉΓòÉ 10. SRPI Return Codes ΓòÉΓòÉΓòÉ

This appendix describes error handling in the SRPI environment. Types 0, 1, 2,
and3 return codes and their definitions are listed. Exception class
definitions, code values, and object values are listed.  Server return codes
are also discussed.

Note:

 1. The Microsoft C Version 6.0 compiler (or its functional equivalent) is
    referred to as C in this appendix.

 2. The Micro Focus COBOL/2 compiler (or its functional equivalent) is referred
    to as COBOL in this appendix.

 3. The Macro Assembler/2 compiler (or its functional equivalent) is referred
    to as MASM in this appendix.


ΓòÉΓòÉΓòÉ 10.1. Error Handling ΓòÉΓòÉΓòÉ

An unsuccessful service request in the SRPI environment can result from
problems at any of the different layers. SRPI shields applications from
transport layer errors as much as possible.  Errors within server processing
are handled by the applications.  The other errors are caused by SRPI and are
treated accordingly.


ΓòÉΓòÉΓòÉ 10.1.1. Transport Layer Errors ΓòÉΓòÉΓòÉ

SRPI tries to recover from transport layer errors. When recovery is not
possible, SRPI returns to the requester with a return code indicating transport
layer failure.  The programmer should handle such failures using the problem
determination procedures of the transport mechanism.


ΓòÉΓòÉΓòÉ 10.1.2. Application Errors ΓòÉΓòÉΓòÉ

SRPI is responsible for routing requests to servers and returning replies to
requesters.  Requesters and servers are responsible for handling errors (except
for abend) that servers encounter.  When a server ends abnormally, SRPI returns
to the requester with an abend notice in the SRPI return code.

The server return code is set by the server on the IBM host computer running
under VM or MVS.  The value and meaning of the server return code is dependent
on the requester or the server.


ΓòÉΓòÉΓòÉ 10.1.3. SEND_REQUEST Processing Errors ΓòÉΓòÉΓòÉ

SRPI return codes can encounter a number of errors in processing the
SEND_REQUEST function.  Such errors include:

o Invalid function parameters
o Unidentified server
o Inability to contact the server
There are also system error codes for internal SRPI errors.


ΓòÉΓòÉΓòÉ 10.2. Types of SRPI Return Codes ΓòÉΓòÉΓòÉ

SRPI return codes include types 0, 1, 2, and 3: .

Type 0       Indicates successful completion of the SEND_REQUEST function.

Type 1       Indicates errors detected by the SRPI router that prevent a
             request from being processed.

Type 2       Indicates errors detected by the SRPI router and reported to the
             remote computer by an acknowledge interchange unit.

Type 3       Indicates errors detected by the remote computer and reported to
             the SRPI router by an acknowledge interchange unit.

The return code values are word-reversed and byte-reversed within each word.
For example, the SRPI return code X'0100 0402' is stored in the CPRB memory as
X'0204 0001'.


ΓòÉΓòÉΓòÉ 10.2.1. Type 0 Return Code Definitions ΓòÉΓòÉΓòÉ

The type 0 return code (constant return code UERERROK) has the following
format: X'0000 0000'. This return code value indicates that the SRPI function
completed successfully.


ΓòÉΓòÉΓòÉ 10.2.2. Type 1 Return Code Definitions ΓòÉΓòÉΓòÉ

Type 1 return codes have the following format: X'0100 nnnn'.

The nnnn bytes are the hexadecimal value that indicates the specific error
detected.

The return code definitions and descriptions are listed in Type 1 Return Code
Definitions and Descriptions.

ΓòÉΓòÉΓòÉ 10.3. Class Definitions for Type 2 and Type 3 ΓòÉΓòÉΓòÉ

The exception classes are syntax, semantic, and process.

o Syntax exception class.

  This class reports violations of the transmission unit syntax rules (for
  example, omitting the server return code parameter: X'0202 1A08'). In
  general, a return code reporting a syntax exception indicates a system
  software error in the SRPI router or in the host.

o Semantic exception class.

  This class reports conflicting parameters (for example, an invalid
  correlation value: X'0203 1B00'). In general, a return code reporting a
  semantic exception indicates a system software error in the SRPI router or in
  the host.

o Process exception class.

  This class reports exception conditions during request processing (for
  example, server unknown: X'0304 1E00').

The exception class definitions are listed in Class Definitions for Type 2 and
Type 3.

ΓòÉΓòÉΓòÉ 12. Connectivity Programming Request Block ΓòÉΓòÉΓòÉ

This appendix describes the connectivity programming request block (CPRB).

Note:

 1. The Microsoft C Version 6.0 compiler (or its functional equivalent) is
    referred to as C in this appendix.

 2. The Micro Focus COBOL/2 compiler (or its functional equivalent) is referred
    to as COBOL in this appendix.

 3. The Macro Assembler/2 compiler (or its functional equivalent) is referred
    to as MASM in this appendix.

The CPRB is used to pass a request to a server.  Requester applications written
in C or COBOL do not require knowledge of the CPRB.

The CPRB fields are described in CPRB Format.

Note:

 1. The SRPI router version ID is used to verify that the provided CPRB format
    can be processed.  If the version ID is not valid, an error code is
    returned in the CPRB.

 2. The following fields should be initialized to the values indicated:

   o CPRB length = Length of the CPRB (X'68')
   o SRPI router version ID = Version number of the router (X'0200')
   o SRPI verb type = X'01'
   o Server name length = X'0008'

    The IBM language support programs provided for C, COBOL, and MASM
    automatically initialize these fields.

 3. The personal computer stores word (2-byte) values in memory in a
    byte-reversed format.  For example, X'0102' is stored in memory as X'0201'.
    Doubleword (4-byte) values are stored in memory in a word-reversed and
    byte-reversed format.  For example, X'0102 0304' is stored in memory as
    X'0403 0201'. The SRPI router does not alter this format when these values
    are sent to the IBM host computer as request data or request parameters.
    When a word value is sent to the IBM host computer, the low-order byte is
    sent first, followed by the high-order byte.  The IBM host computer does
    not use the byte-reversed format.  You must ensure that data and parameters
    passed between the requester and the server are in the proper format for
    the requester or the server.

 4. SRPI router pointers are stored using the doubleword format.  See Note 3.
    The first word in memory contains the offset value for the field.  The
    second word in memory contains the selector value for the field.  For
    example, a pointer with a selector value of X'1E00' and an offset value of
    X'0100' is stored in memory as X'0001 001E'.

 5. The return code values are defined as doublewords by the provided IBM
    language interface.  For example, the SRPI return code X'0100 0402' is
    stored in the CPRB memory as X'0204 0001'.

 6. The version ID must be set to X'0200' if you are using Notification of 3270
    screen update indicator.

 7. If the Notification of 3270 screen update indicator is set to X'FF', SRPI
    does not notify the user when a 3270 screen update blocks transmission of
    data. If set to X'00', SRPI notifies the user when a 3270 screen update
    blocks transmission of data. Other values are invalid and result in a
    return code of X'0100 0622'.

    The Notification of 3270 screen update indicator (uer3270ind) can be
    overridden by an SRPI configuration option.  If you select No for this
    option, the SRPI feature will not provide notification that a 3270 session
    requires attention because of unsolicited messages, regardless of the value
    specified in uer3270ind.

    A requester can use a 3270 emulation API (such as EHLLAPI) to detect and
    respond to 3270 screen updates.  This requester notifies the user directly
    or handles the situation itself.
