- Z3LIB, the ZCPR3-specific libraries, provide:
- Access to the ZCPR3 Environment - (Command Line, CRT/PRT Data, External
- FCB, Environment, FCP Address, File
- Names, Initialize)
- Access to the ZCPR3 Environment - (IOP, DU/Max DU, Messages, Named Dir,
- Path, Processor Speed, Quiet Flag,
- RCP Address, Shell Stack, Wheel Byte)
- Flow and ZEX Control Under ZCPR3
- Access to the ZCPR3 Messages
- General-Purpose ZCPR3 Utilities

- Introduction - 1/2
-
- Z3LIB is one of three libraries provided with the ZCPR3 System, the other
- two being SYSLIB and VLIB. Z3LIB contains a host of support utilities which
- provide access to ZCPR3-specific features and capabilities. SYSLIB is a host
- of general-purpose utilities and VLIB is a set of machine-independent (via
- Z3TCAP) utilities which support CRT control and utilitization.
-
- SYSLIB is documented in a collection of SYSLIB*.HLP files, as is VLIB.
-
- Introduction - 2/2
- Z3LIB routines can be divided into four categories:
-
- 1. ZCPR3 Environment Access
- -- Those utilities which allow the programmer to easily extract
- data from the Z3 Environment Descriptor and modify certain Z3 environment
- parameters
-
- 2. ZCPR3 Flow Control
- -- Those utilities which permit the programmer to easily
- manipulate the flow control environment of ZCPR3, enabling him to raise the
- level or lower the level of the current IF condition and to toggle the current
- IF condition as desired
-
- 3. ZCPR3 Messages
- -- Those utilities providing access to the ZCPR3 messages,
- allowing the program to read and write messages from and to the system
-
- 4. ZCPR3 Utilities
- -- Useful utilities which relieve the programmer from
- constantly reprogramming some commonly-used ZCPR3 features

- Extended Environment Description
-
- Version 4 of Z3LIB incorporates many enhanced functions developed by Joe
- Wright and Jay Sage in NZCOM and ZCPR33 and 34. Due to redefinition of some
- of the bytes in the Environment Descriptor, a few of the original modules will
- not perform as originally intended. For example, only one Console (CRT
- device) is supported. The remaining space in the ENV contains vectors to
- system segments.
-
- Some programs such as Plu*Perfect Systems' JETLDR and Alpha Systems' NZCOM
- set an existing Environment Descriptor to reflect the necessary extended
- definitions. If you do not routinely use either of these products, you should
- create a new SYS.ENV file for use with your existing ZCPR3 system. The new
- definitions are marked with an asterisk (*) in the following source code
- sample Environment Descriptor.
