Qedit is a high performance, full-screen text editor available from Robelle Solutions Technology Inc. for all models of the HP e3000 computer system. Qedit files exist in a special compressed format which can only be read by Qedit or software such as Qcopy that has been modified to read them. Qcopy is used to convert files to and from Qedit's special format. Along with Qcopy we provide a stand-alone routine named Qeditaccess that provides the actual decoding of Qedit files. You may merge this routine into your own programs if you wish. See below for details. The code is available in both compatibility -mode and native-mode formats. Qcopy is also used to recover Qedit files that have been corrupted. While this happens rarely, Qcopy is the only program that can recover the lines of a Qedit file. ___ ________ __ _______ ___ _________ ______ New Features in Version 4.7 (November 2003): * Qcopy and Qaccess now support the TrailingSpaces option in Qedit workfiles. ___ ________ __ _______ ___ ________ ______ New Features in Version 4.6 (October 2002): * Qeditaccess can read TEXT files with lines of up to 8,172 characters wide. If the file is wider, Qeditaccess returns only the first 8,172 characters and ignores the rest. Qedit workfiles are limited 1,000 characters i.e. Jumbo workfiles. Trying to access wide-jumbo workfiles now returns an error: -9 for "Qaccess: Wide jumbo workfiles not supported yet." _______ _ _______ __ _____ 2 Chapter 1 Welcome to Qcopy ___ ________ __ _______ ___ _________ ______ New Features in Version 4.5 (February 1998): * Qeditaccess no longer misses the last few lines in a Jumbo file. ___ ________ __ _______ ___ ________ ______ New Features in Version 4.4 (January 1997): * Fixed Qeditaccess bug in exceeding record sizes. ___ ________ __ _______ ___ __________ ______ New Features in Version 4.3 (September 1995): * Qeditaccess can read Jumbo text files greater than 256 characters wide. ___ ________ __ _______ ___ _______ ______ New Features in Version 4.2 (August 1994): * Qeditaccess has been upgraded to read Qedit's new Jumbo workfiles. However, Jumbo files with a record length of more than 256 characters are rejected by the existing open functions (this is for backward compatibility). If you are willing to accept any record size in your program, use functions 30 to 32: 30 - open a file with any record size. 31 - pass in a filenum already opened (any record size). 32 - open a file with any record size, read serially. * There are three new error numbers: -6 for "Qaccess: Invalid format for Jumbo Qedit file" -7 for "Qaccess: use Jumbo Open (func 30) if rec>256" -8 for "Qaccess: Write/Append to jumbo not impl yet" Qeditaccess does not yet write Jumbo files. ________ __ _____ Overview of Qcopy Qcopy expects commands in a format that is similar to FCOPY. The ________ ______ fromfile is specified by FROM= and the tofile is specified by TO=. The TO= portion can be left off, in which case Qcopy copies the ________ fromfile into itself, converting it from Qedit format to Keep format. Qcopy can copy a group of files with a single command. _______ _____ Refer to the chapter Copying Files for more information. Qcopy interprets any command line beginning with a colon (:) as an MPE command. Only the commands that MPE allows in "break" are _______ _ _______ __ _____ Chapter 1 Welcome to Qcopy 3 allowed in Qcopy. This feature can be used to :PURGE any files, obtain a :LISTF of files, or to include :COMMENT lines. For information on Qcopy and Qeditaccess, use the Help command. All of the information in the Qcopy user manual is available on-line through the Help command. For help on new features recently added to Qcopy, type "Help News". The Help command can be abbreviated to "?". ___ __ ___ _____ How to Run Qcopy We include two copies of the Qcopy program: Qcopy.Qlib and QcopyNM.Qlib, which is a native-mode version for MPE/iX systems. To install the native-mode version of Qcopy as the production version, use these commands: :hello mgr.robelle,qlib :rename qcopy,qcopycm :rename qcopynm,qcopy To access Qcopy, type this command: :run Qcopy.Qlib.Robelle Qcopy prints its version number and prompts with ">". You type commands, ending each command with Return. For example, type "HELP": >help Qcopy prints some help text and a keyword list. Type a keyword, or press Return to leave Help and return to Qcopy. Qcopy accepts commands from $STDINX, the standard MPE job input file. This is usually the terminal or the stream file. You can redirect the input by using the STDIN option of the :RUN command. Qcopy writes all messages to $STDLIST, the standard MPE job listing file. You can redirect the output by using the STDLIST option of the :RUN command. Qcopy can be run in batch, but Qcopy will abort if an error occurs. To leave Qcopy, type "EXIT" or "E". __________ _____ Suspending Qcopy When you run Qcopy from Qedit or Select, Exit suspends Qcopy so that it can be re-activated quickly later. If you run Qcopy from within HPDESK (and some other programs), Qcopy will suspend on Exit but HPDESK will not notice. The next time you run Qcopy, HPDESK will create a new copy of the program. Eventually you will _______ _ _______ __ _____ 4 Chapter 1 Welcome to Qcopy have many suspended copies of Qcopy hanging from HPDESK, consuming system resources. You can force Qcopy to terminate on Exit rather than suspend by running Qcopy with PARM=32. :run qcopy.qlib.robelle;parm=32 5 _______ _ _______ _____ Chapter 2 Copying Files _ _______ ______ __ _____ * Copying Groups of Files _ _______ * Options _ ________ * Examples The command used to copy files is: ________ ______ _______ FROM = fromfile ; TO = tofile ; options ________ The FROM=fromfile portion is the only part that is required. ________ Qcopy opens the fromfile as an old disc file with read access. It can be any Qedit workfile, or any standard Keep file with fixed-length or variable-length records. ________ Qcopy reads each record in the fromfile and transfers it to the ______ ________ tofile. When the fromfile is a Qedit workfile, the resulting file corresponds to what you would get by doing a Keep of a Qedit workfile from within Qedit. Where appropriate, line numbers are ______ included in each record of the tofile (columns 1-6 in COBOL, columns 73-80 for SPL, FORTRAN, or Pascal, and no line number for RPG, JOB and TEXT files, unless 'SERIAL' is specified). If the entire TO= portion of the command line is not specified, ________ the fromfile is copied into itself. WARNING: you need save ________ access to the group and account of the fromfile in this case. ______ If the tofile file name is not specified, the records are printed ______ on $STDLIST. If the tofile file name is specified, it is opened OLD with WRITE access, unless the 'NEW' or 'Qedit' option is specified. When the copy operation completes, Qcopy displays the number of records that were copied. Qcopy then prompts for another command. This continues until :EOF on $STDINX or you enter the "EXIT" command. You can interrupt a copy operation by pressing control-y. This will stop the copy immediately. The current file being copied will be closed and Qcopy will display the number of records that were written to the file before the copy operation was interrupted. _______ ______ __ _____ Copying Groups of Files Qcopy can copy an entire group of source files to another group or back into itself. The syntax to copy from one group to a different group is: _________ _______ >FROM=@.fromgroup;TO=@.togroup;NEW _______ _ _______ _____ 6 Chapter 2 Copying Files The syntax to convert an entire group from Qedit format to Keep format is: _________ >FROM=@.fromgroup _________ For each file in the fromgroup, a file with the same name is _______ created in the togroup. We recommend that you clear out the _______ togroup first with a :PURGEGROUP command. To interrupt a group copy operation, press control-y. This will stop the copy immediately. The current file being copied will be closed and Qcopy will display the number of records written to the file before the copy operation was interrupted. The group copy option can be combined with the 'INCLUDE' option to provide a very convenient mechanism for distributing SPL, FORTRAN, or Pascal applications in source code: 1. Use $INCLUDE for all FILE or DATASET record layouts and common blocks in FORTRAN. 2. Publish the names of the include files for your users. 3. Distribute your source code in Qedit form in a special group. This saves disc space. 4. Users who want to replace or expand the DATASET layouts, may replace the appropriate 'INCLUDE' files, which can be either Qedit or Keep files, and :RUN Qcopy to move the entire group or selected programs to another group. The customized source code is compatible with EDIT/3000. 5. If your users have Qedit, they can dispense with the Qcopy operation completely and let the $INCLUDE operation happen at compile-time, with the same customizing results. _______ Options The options to Qcopy must be separated by semi-colons and are taken from the following list: _______ options = NEW INCLUDE UNN ERASE APPEND SERIAL QEDIT FTN ___ ______ NEW Option ______ By default, the tofile is an OLD disc file. When the NEW option ______ is specified, the tofile is opened as a new disc file. In this ______ ___ case, the tofile must not exist. If it does, Qcopy will fail when ______ ______ it tries to close the tofile. If no TO= is specified, the tofile is opened as a new disc file. _______ _ _______ _____ Chapter 2 Copying Files 7 _______ ______ INCLUDE Option The 'INCLUDE' option causes Qcopy to look for $INCLUDE records and replace them by the lines of the specified file. ________ $INCLUDE filename ______ Qcopy adds 10000 to the size of the tofile in order to allow room for the included lines. If you do not specify the 'INCLUDE' option, the lines that start with $INCLUDE are copied to the ______ tofile without any change. ______ If you try to TEXT the tofile into EDIT/3000, it will detect that the sequence fields in the included lines are out of sequence, and treat the file as an unnumbered file. You may have to set right=72 and length=72 to eliminate the sequence fields. With Qedit, the file is automatically resequenced starting with the first included line. ___ ______ UNN Option This option causes the Qedit file to be read without sequence numbers in each line. By default, Qedit files have sequence numbers unless the Language is Job, RPG or Text. _____ ______ ERASE Option ______ This option specifies that the tofile is an old file whose contents are to be overwritten. This may seem like a useless option, since Qcopy overwrites old files by default (unless you specify the NEW or QEDIT options), but it isn't. The ERASE option is the only way you can get Qcopy to erase and overwrite a Qedit workfile. ______ ______ APPEND Option ______ This option specifies that the tofile is an existing file that you want to append lines to. The old file may be a Qedit file or a Keep file. _____ ______ QEDIT Option Normally, Qcopy reads a Qedit file and creates a standard Keep file. The QEDIT option reverses this by reading a Keep file and creating a Qedit file. ____ This option only works for new files (the NEW option is assumed). With this option there is no way to write over an existing file. Use the ERASE option instead if you want to write over an existing Qedit file. This option also works with group copies. _______ _ _______ _____ 8 Chapter 2 Copying Files ___ ______ FTN Option Qcopy has no method of distinguishing FORTRAN or Pascal Keep files from SPL Keep files. All Keep files with record numbers in the last eight columns are assumed to be SPL files. If you want the new Qedit files to be identified as FORTRAN files instead of SPL (when it is ambiguous), use the FTN option with the Qedit option. This changes the default language when converting Keep files with 8-byte sequence numbers. ___ ______ PAS Option This option is similar to the FTN option, except that it sets the default language to Pascal when converting Keep files. ________ Examples 1. Convert a Qedit file to Keep format. In this case the output ____ file must exist. :run Qcopy.qlib.robelle >from=qfile;to=kfile >exit 2. Convert a Qedit file to Keep format, but the output file does not already exist: :run Qcopy.qlib.robelle >from=qfile;to=kfile;new >exit 3. Convert a Qedit file with $INCLUDE lines to Keep format. The $INCLUDE files will be copied to the output file at the correct place. The output file does not already exist. :run Qcopy.qlib.robelle >from=qfile;to=kfile;new;include >exit 4. Convert a Qedit file into Keep format by copying it back into itself. :run Qcopy.qlib.robelle >from=qfile >exit _______ _ _______ _____ Chapter 2 Copying Files 9 5. Copy an entire group of Qedit files to another group, converting each file to Keep format. First, we logon in the destination group and use the :PURGEGROUP command to purge all of the existing files. Because we are logged on in the group ___ we are purging, the group will not be purged, only the files will be. :hello mgr.dev,ksource :purgegroup ksource :run Qcopy.qlib.robelle >from=@.qsource;to=@.ksource;new >exit 6. Copy an entire group into itself. This converts each Qedit file in the group to Keep format. :hello mgr.dev,qsource :run Qcopy.qlib.robelle >from=@.qsource >exit ______ 7. Convert a Keep file to Qedit format. The tofile must not already exist: :run Qcopy.qlib.robelle >:purge qfile >from=kfile;to=qfile;qedit >exit 8. Convert an entire group from Keep format to Qedit format. Each source file will be converted. Binary files will be ignored, but ASCII data files will be converted to Qedit format: :hello mgr.dev,ksource :run Qcopy.qlib.robelle >from=@.ksource;qedit >exit ______ 9. Convert a FORTRAN Keep file to Qedit format. The tofile must not already exist: :run Qcopy.qlib.robelle >:purge qfile >from=kfile;to=qfile;qedit;ftn >exit 10 _______ _ ________ _____ ___ ______ ______ Chapter 3 Recovery Using the SERIAL Option _ ____________ * Introduction _ ________ * Examples ____________ Introduction The "SERIAL" option is used to recover Qedit workfiles that have been corrupted. Qedit workfiles have an internal linkage structure that keeps all of the lines in line number order. It is possible that through a system crash these pointers could be incorrect. When this happens, Qedit goes through a recovery procedure. It is possible that the Qedit recovery will fail. In this case, use 'SERIAL' to recover the file. The SERIAL option causes Qcopy to read records from the Qedit workfile in serial order. Qcopy ignores the internal linkage pointers of the workfile. Of course, the resulting lines will not be in the correct order. ______ ______ When using this option, the tofile will always have sequence numbers. This means that 88-byte records will be generated for JOB/RPG files, with sequence numbers in columns 81 through 88, and 264-byte records for TEXT files, with sequence numbers in columns ______ 257 through 264. The tofile must then be sorted by sequence number in order to put the records back in their correct order. ________ Examples 1. Recovery of a COBOL or a COBOLX file: :run Qcopy.qlib.robelle >:purge k >:purge ksorted >from=cobprog;to=k;new;serial >exit :comment k = unsorted lines of cobprog :run sort.pub.sys >input k >output ksorted >key 1,6 >end :comment ksorted contains recovered cobprog. :run Qedit.pub.robelle /t cobnew=ksorted If there are any duplicate lines, Qedit prints WARNING: Linenum _______ _ ________ _____ ___ ______ ______ Chapter 3 Recovery Using the SERIAL Option 11 and renumbers the lines after the first duplicate line. 2. Recovery of a SPL, FORTRAN, or Pascal file: :run Qcopy.qlib.robelle >:purge k >:purge ksorted >from=splprog;to=k;new;serial >exit :run sort.pub.sys >input k >output ksorted >key 73,8 >end :run Qedit.pub.robelle /t splnew=ksorted 3. Recovery of a RPG or JOB file: :run Qcopy.qlib.robelle >:purge k >:purge ksorted >from=jobprog;to=k;new;serial >exit :run sort.pub.sys >input k >output ksorted >key 81,8 >end :run Qedit.pub.robelle /t jobnew=ksorted 4. Recovery of a TEXT file: :run Qcopy.qlib.robelle >:purge k >:purge ksorted >from=textprog;to=k;new;serial >exit :run sort.pub.sys >input k >output ksorted >key 257,8 >end :run Qedit.pub.robelle /t textnew=ksorted 12 _______ _ ___________ _________ Chapter 4 Qeditaccess Procedure _ ____________ * Introduction _ ________ _________ * Function Parameter _ _________ _________ * Workspace Parameter _ ________ _________ * Argument Parameter _ ______ _______ __ _______ _ _____ ____ * Pascal Example of Reading a Qedit File _ ___ _______ __ _______ _ _____ ____ * SPL Example of Reading a Qedit File _ _____ _______ __ _______ _____ __ ___ * COBOL Program to Convert Qedit to MPE _ _____ _______ __ _______ ___ __ _____ * COBOL Program to Convert MPE to Qedit ____________ Introduction Qeditaccess is a general-purpose interface routine that can be called by a user program written in COBOL, FORTRAN, SPL, or Pascal. It is used to access source files in programs such as text formatters, assemblers, compilers, cross references, and so on. It will open, read, rewind, and close any ordinary source file. It also supports these same functions for Qedit workfiles, making them look to the user program as if they were normal source files with fixed-length records. Other functions of Qeditaccess: find by line number function for Qedit files only, open new Qedit file, open old Qedit file (and erase), write to Qedit file, close as permanent file, and close as temporary file. A shorter name, QACCESS, is provided for programs written in Pascal Robelle (or any other language that restricts the length of identifiers). Qeditaccess is a routine of the Qcopy program, but it is also distributed separately in both object and source format (qaccess.qlibsrc.robelle). Qeditaccess may be used by anyone who wants their software to read Qedit workfiles; it may be used in software products provided that both Qedit and Robelle are acknowledged in the product documentation. We also recommend that anyone who is using Qeditaccess and is not a customer of Robelle should inform us that Qeditaccess is being used. Robelle reserves the right to change the format of Qedit workfiles and the code to ___ Qeditaccess at any time in the future. Qeditaccess is declared in an SPL program as: Procedure Qeditaccess ( Function, Workspace, Argument ); Integer Array Function; Array Workspace, Argument; Option External, Check 2; All parameters are passed by reference so that Qeditaccess can be called from COBOL programs. For details on how to call Qeditaccess from SPL, Pascal and COBOL, refer to the examples below. _______ _ ___________ _________ Chapter 4 Qeditaccess Procedure 13 When using any of the read functions (2, 8 or 17), the Argument parameter is a buffer where the data is going to be stored. Qaccess returns up to 8,172 characters for text files. If the file records are wider, Qaccess truncates the records. If the buffer is too small for the requested text, the result is unpredictable. The limit is 1,000 characters for Qedit workfiles (jumbo). If you are trying to access wide-jumbo workfiles, Qaccess returns an error (-9). ________ _________ Function Parameter Although Function is defined as an integer array, it is only used as a single word integer, PIC S9(4) COMP in COBOL, except in functions 9 to 16. The first word of Function tells Qeditaccess what task to perform. The valid function values are 1 through 18, plus 30 and 31. _______ __ ________ ___ ________ Summary of Function and Argument Function Use Argument 1 Open a file for read filename 2 Read the next record line read 3 Close file after reading unused 4 Rewind unused 5 Serial open for read filename 6 Find line number line number (in) line read (out) 7 Already open for read file number 8 Read unnumbered line read 9 Open new Qedit file filename 10 Save/Close as permanent file unused 11 Save/Close as temporary file unused 12 Write line line to write 13 Open for write, erase filename 14 Already open for write, erase file number 15 Open for write, append filename 16 Already open for write, append file number 17 Read line line read 18 Explain error number message 30 open for read, any reclen filename 31 already open for read, any rec filenum 32 open for serial read, any rec filename __ ____ _ _____ ___ ____ ____ ______ 1. Open a file, OLD with READ access Argument contains the file name, which may be a Qedit or Keep file, permanent or temporary. See word 5 of the Workspace (e.g., Workspace(4) in SPL) for the record length in bytes of the file. Files with record lengths longer than 256 characters _______ _ ___________ _________ 14 Chapter 4 Qeditaccess Procedure are rejected, since previous versions specified that as the maximum size of the Argument parameter on read calls. Use Functions 30 or 31 to access files or any record size. __ ____ ___ ____ ______ 2. Read the next record The record is returned in Argument. If the file is a Qedit file that we think of as numbered (e.g., COBOL, SPL, FORTRAN, or Pascal), the line number will be formatted in ASCII just like an EDIT/3000 Keep file. The length of the record read is returned in word 10 of the Workspace. For Qedit files, the line number is also returned as a 32-bit integer in Words 6 and 7 of the Workspace parameter. ____ If the file was opened with function 1, the next record is the next logical record in the file (i.e., in line number ____ sequence). If the file was opened with function 5, the next record is the next physical record in the file (i.e., MPE record sequence). __ _____ ____ _____ _______ 3. Close file after reading Use this function with read-access files (functions 1, 5, and 7). Argument is unused. __ ______ 4. Rewind Rewind the file to the beginning in preparation for reading again. Argument is unused. __ ______ ____ 5. Serial Open Open the file for serial read access. This function is used with the 'SERIAL' option of Qcopy described previously. __ ____ ____ ______ 6. Find Line Number Find the line with a line number greater than or equal to the line number specified in Argument. The target line is specified as a 32-bit INTEGER or S9(9) COMP in COBOL. The line itself is returned in the same Argument parameter, so be sure to allow room. The line number of the line found is returned in words 6 and 7 of the Workspace parameter. If the line number target is higher than the last line in the file, -1 is returned in the Status word of the Workspace. Remember that line 1 is really line 1.000 or 1000 when stored as a 32-bit INTEGER. ____ ________ ____ _____ ___ _____ _____ This function only works for Qedit files (word 3 of the _______ _ ___________ _________ Chapter 4 Qeditaccess Procedure 15 Workspace' must be 1, not 0 or 2) that are open for read access. __ _______ ____ 7. Already Open Argument contains the file number of a file that you have already opened with FOPEN for read access. This function is like function 1, except that you do the FOPEN yourself. With this function, you can choose to call Qeditaccess only if the filecode is 111 (instead of for every file). __ ____ __________ 8. Read Unnumbered For Keep files, this function is just like function 2. For Qedit files, the sequence number is not returned as part of the line. Instead, Words 6 and 7 of the Workspace contains the sequence number. Word 10 of the Workspace (e.g., Workspace(9) in SPL) contains the length in bytes of the line just returned (less trailing blanks). Argument always returns a fixed-size record with trailing blanks. For COBOL Qedit files, the first character returned is column 7. If you want to read Keep files the same way as Qedit files, use function 17. __ ____ ___ _____ ____ 9. Open New Qedit File Function is an integer array that describes the new file. For SPL calls, subtract 1 from offsets. Function(1) = 9, Open New Qedit file Function(2) Language 1=SPL, 2=Ftn, 3=COBOL, 4=RPG, 5=Job, 6=Text, 7=Pascal, 8=CobolX, 9=Data Function(3) Recsize in bytes, needed if Language=6 (text) Function(4) Number of Blocks, allow Lines/8 blocks Function(5) Number of Extents (1-32) Function(6) Initial Extents (1-number of extents) Argument contains the name of the new file. Qeditaccess opens the new file and prepares to write lines into it (see function 12). If the file is a duplicate, you will not find out until you try to close it (see function 10 or 11). _____________ __ _________ ____ 10.Save/Close As Permanent File Closes the current write-access file as Save-Permanent. Use this function, not function 3, with functions 13 to 16 (old files, write-access) and and with function 9 (new Qedit file). For new Qedit files, function 10 will fail if the file already _______ _ ___________ _________ 16 Chapter 4 Qeditaccess Procedure exists. Argument is unused. _____________ __ _________ ____ 11.Save/Close As Temporary File Closes the new Qedit file (see function 9 above) as an old temporary file.

Argument is unused. ________ ____ 12.Write Line Writes a new line to the end of a Qedit file that has been opened for write access (functions 9, 13, 14, 15, 16). Argument contains the variable-length data for the new line. Function is an integer array that defines the byte length of the new line and the line number. For SPL subtract 1 from offsets. Function(1) = 12, Write new line Function(2) Recsize in bytes, positive Function(3/4) Line number, 32-bit integer, line 5 is 5000 Pass zero (0) every time if you would like Qeditaccess to assign line numbers itself _______ ___ ______ _____ 13.Open For Write, Erase Argument contains the name of an existing Qedit or Keep file to open. The existing contents of the file will be destroyed. Function is an integer array that describes what type of data you plan to write into the file. For SPL, subtract 1 from offsets. Function(1) = 13, Open for Write, Erase Function(2) Language 1=SPL, 2=Ftn, 3=COBOL, 4=RPG, 5=Job, 6=Text, 7=Pascal, 8=CobolX, 9=Data Function(3) Recsize in bytes, needed if Language=6 (text) __________ ____ ___ ______ _____ 14.Already Open For Write, Erase This is just like function 13, except that the caller opens the file.

The existing contents of the file will be preserved. Function is an integer array that describes what type of data you plan to write into the file. If the existing ___ file is a Qedit workfile and empty, Qeditaccess gives it the Language and Length you specify. If the file contains lines or is not a Qedit file, Qeditaccess ignores your requested Language and Length. For SPL, subtract 1 from offsets. Function(1) = 15, Open Existing File to Append Function(2) Language 1=SPL, 2=Ftn, 3=COBOL, 4=RPG, 5=Job, 6=Text, 7=Pascal, 8=CobolX, 9=Data Function(3) Recsize in bytes, needed if Language=6 (text) __________ ____ ___ ______ ______ 16.Already Open For Write, Append Argument contains the file number of an existing Qedit or Keep file that the caller has opened. Qeditaccess accepts it for append access. To append to a Qedit file you must open the file with Read/Write access. Function is an integer array that describes what type of data you plan to write into the file. ___ If the existing file is a Qedit workfile and empty, Qeditaccess gives it the Language and Length you specify. If the file contains lines or is not a Qedit file, Qeditaccess ignores your requested Language and Length. For SPL, subtract 1 from offsets.

Argument returns a fixed-size record with trailing blanks. The sequence number is removed from the line, and words 6 and 7 of the Workspace contain the sequence number. If the file is unnumbered, the sequence number returned starts at 1.000, then 2.000, etc. Word 10 of the Workspace contains the byte length of the line read (less trailing blanks). _______ _ ___________ _________ 18 Chapter 4 Qeditaccess Procedure __________ 18.Explain Put a one-line explanation of the Workspace status into Argument. Word 10 of the Workspace contains the length of the explanation in bytes. _______ _ ____ __ ___ _______ ____ ____ ______ 30.Open a file of any Recsize with READ access Function 30 is identical to function 1, except that a file record length of more than 256 characters is allowed. Argument contains the file name, which may be either a permanent or temporary Qedit or Keep file. See word 5 of the Workspace (e.g., Workspace(4) in SPL) for the record length in characters. You must provide a buffer of at least this size in any read calls that you make. __________ ________ _______ ____ 31.Anysize Records, Already Open Function 31 is identical to function 7, except that a record length of more than 256 characters is allowed. See word 5 of the Workspace (e.g., Workspace(4) in SPL) for the record length in characters. You must provide a buffer of at least this size in any read calls that you make. Argument contains the file number of a file that you have already opened with FOPEN for read access. This function is like function 1, except that you do the FOPEN yourself. With this function, you can choose to call Qeditaccess only if the filecode is 111 (rather than for every file). ______ ______ ____ _ ______ ____ 32.Any Record Size - Serial Open Open a file with any record size for serial read access. See word 5 of the Workspace (e.g., Workspace(4) in SPL) for the record length in characters. You must provide a buffer of at least this size in any read calls that you make. This function is used with the Serial option of Qcopy, which is described elsewhere. _________ _________ Workspace Parameter The Workspace is a 270-word (540-byte) array that must be provided for each file to be opened. This array is used to hold the MPE file number and other information about the file. In addition, it returns the status of the last operation. The words of the array are defined as follows. _______ _ ___________ _________ Chapter 4 Qeditaccess Procedure 19 _______ __ _________ __________ Summary of Workspace Parameters Offset Contents Explanation word 1 Status MPE error number of last operation, or 0 if ok, or -1 for end of file Qeditaccess errors are negative numbers word 2 Filenum MPE filenumber returned by FOPEN Can be used to call print'file'info word 3 Type 0=Keep file, 1=a Qedit file, 2=other, 3=new Qedit file, 4=erase MPE file, 5=append MPE file, 6=erase Qedit file, 7=append Qedit file word 4 Lang 0=unknown, 1=spl, 2=ftn, 3=cob, 4=rpg, 5=job, 6=text, 7=pascal, 8=cobolx, 9=data word 5 Length The record length in bytes For variable length files, the maximum possible length of a record word 6/7 Size or OPEN function, number of lines in file Curkey FIND function, line number of this line READ functions, line number of line word 8 Block Current disc block (Qedit regular files only) word 9 Index Current index into block (Qedit only) word 10 Readlen Length in bytes of last record read word 11 Left 0=linenum at right end of record 1=linenum at left end of record word 12 Keylen Length of the line number key in bytes word 13/14 reserved for internal use word 15-270 buffer space for Qedit file __ ______ 1. Status This contains the MPE error number of last Qeditaccess operation. You can use this value to call ferrmsg. A 0 indicates no error, and end of file is indicated by a -1. A negative error number indicates an internal Qeditaccess error. -1 End of file. -2 File record length greater than 256. _______ _ ___________ _________ 20 Chapter 4 Qeditaccess Procedure -3 File system error reading block one, Fcheck unable to find error. -4 Invalid function. -5 File system error, Fcheck unable to find error. -6 Invalid format for Jumbo Qedit file. -7 Use Jumbo Open (func 30) if rec>256 -8 Write/Append to Jumbo not implemented yet. 72 This error commonly occurs when you try to use a function not compatible with the way the file is opened (e.g., writing to a file opened for read). __ ____ ______ 2. File number This contains the MPE filenumber returned by FOPEN. You can be used it to call print'file'info. __ ____ ____ 3. File type This contains the type of the file detected by Qeditaccess after you call one of the Open functions. 0 Keep file 1 Qedit file 2 Other/Binary 3 New Qedit file 4 Erase MPE file 5 Append MPE file 6 Erase Qedit file 7 Append Qedit file __ ________ 4. Language This contains the language type of the file. For the Open or Read functions, Qeditaccess tries to determine the language of the file by looking at the first record. For the Open for Write functions, this contains the language that you passed via the Function parameter. 0 Unknown 1 SPL 2 Fortran 3 Cobol 4 RPG 5 Job 6 Text 7 Pascal 8 CobolX 9 Data _______ _ ___________ _________ Chapter 4 Qeditaccess Procedure 21 __ _______ 5. Recsize This contains the maximum length of a record in the file. For Qedit files, this depends on the language of the file. For Keep files, this is the length of each record. For variable length files, this is the longest record that could be in the file. If you just converted a file into variable length format, then this value is likely going to be much larger than the longest actual record. ________ ____ __ ____ ______ 6,7.File Size or line number This 32-bit integer could contain several values, depending on which Qeditaccess function was called. After an OPEN function, this contains the number of lines in file. After a FIND function, this contains the line number of the found, which may be different than the line you requested if you specified a non-existent line. After a READ function, this contains the line number of the line just read. __ _____ _____ 8. Qedit Block This contains the block number of the current disc block. This is only valid for Qedit files. __ _____ _____ 9. Qedit Index This contains the current index into the current disc block. This is only valid for Qedit files. _______ ______ 10.Read Length This contains the length in bytes of the last record read. For Qedit files, this is the length of the line without trailing blanks. For Keep and variable length files, this depends on which Read function was called. For Read functions 2 and 8, this is the length of the actual record read. For Read function 17, this is the length of line without line numbers and without trailing blanks. You should use Read Length instead of Recsize when you access the record. _______ ____ 11.Left Flag This contains a flag indicating where the line number is in a record. For most MPE files (except COBOL), the line number is at the end of the record. COBOL files have line numbers at the beginning of the record. 0 Linenum at right end of record _______ _ ___________ _________ 22 Chapter 4 Qeditaccess Procedure 1 Linenum at left end of record ______ ______ 12.Key Length This contains the length of the line number key in bytes. For COBOL, the line number is 6 bytes long. For other languages, the line number is 8 bytes long. ______ ________ ___ ________ ___ 13,14. Reserved for internal use _______ ______ _____ ___ _____ _____ 15-270. Buffer space for Qedit files ________ _________ Argument Parameter This is a general-purpose parameter. In functions 1, 5, 9, 13 and 15, it specifies the file name to be opened. In functions 2, 8, and 17, it is the buffer for returning the record just read. In function 12, it is the buffer containing the data to be written. In function 6, it is a line number in DOUBLE-INTEGER format. In functions 7, 14 and 16, it passes in the file number (single integer). In function 18, it contains the error message that is returned. For the other functions that doesn't use the Argument, a dummy parameter still must be passed. ______ _______ ________ _____ _____ Pascal Example (Reading Qedit File) { This program demonstrates how to call Qeditaccess from Pascal. It reads a Qedit file called QDATA and displays the contents of the file on $stdlist. } $HP3000_16$ { compiler option for Pascal/XL only } program TestQaccess( input,output ); const MaxFnameLen = 40; MaxLineLen = 256; type shortint = -32768..32767; { The type declaration for shortint is required in Pascal/V. Comment this line out in Pascal/XL. } { This is the general Argument parameter for Qeditaccess. The different uses are indicated by the variant fields. More variant fields can be added. _______ _ ___________ _________ Chapter 4 Qeditaccess Procedure 23 All of the parameters must be passed as 16-bit word addresses (e.g., the Argument parameter cannot simply be declared as a packed array of char) The case variant shortint MUST NOT be given a field name. } ArgRec = record case shortint of 1: (fname: packed array[1..MaxFnameLen] of char); 2: (line: packed array[1..MaxLineLen] of char); end; WorkRec = record status : shortint; filenum : shortint; filetype : shortint; lang : shortint; length : shortint; size_key : integer; block : shortint; index : shortint; readlen : shortint; left : shortint; keylen : shortint; reserved : integer; buf : packed array[1..256] of shortint; end; FuncRec = record num : shortint; lang : shortint; recsize : shortint; numblocks : shortint; numextents : shortint; initextent : shortint; end; var Func : FuncRec; WorkSpace : WorkRec; Arg : ArgRec; i : shortint; done : boolean; procedure QeditAccess( var func : FuncRec; var workspace : WorkRec; var arg : ArgRec ); external spl; begin arg.fname := 'QDATA '; Func.num := 1; QeditAccess( Func, WorkSpace, Arg ); _______ _ ___________ _________ 24 Chapter 4 Qeditaccess Procedure if WorkSpace.status<>0 then begin writeln('could not open, error = ', WorkSpace.status ); end else begin done := false; repeat Func.num:=2; QeditAccess( Func, WorkSpace, Arg ); if WorkSpace.status=0 then begin for i:=1 to WorkSpace.length do write( Arg.line[i]); writeln; end else if WorkSpace.status=-1 then { end of file } done := true else begin writeln('could not read, error = ' ,WorkSpace.status); done := true; end; until done; Func.num := 3; QeditAccess( Func, WorkSpace, Arg ); end; end. ___ _______ ________ _____ _____ SPL Example (Reading Qedit File) $control uslinit begin << Qcopytst program: testing Qeditaccess routine.
