- PXREF
- Pascal Cross Reference Program

- Version 1.0

-
- INTRODUCTION
-
- This program generates a listing of a pascal program and a cross
- reference listing of the variables, procedures & functions, built-in
- procedures, and key words.
-
- The listing can be output to disk, printer ports, or serial ports.
- Any section of the output can be enabled or disabled. In addition,
- only symbols with a single reference can output to help find
- unreferenced variables in a program.
-
- The program defaults can be set in a setup file. Settings can be
- overridden with command line parameters. File names can be specified
- on the command line for batch operation, or can be entered when the
- program is run.
-
- This program is compatible with both Turbo Pascal files and Microsoft
- Pascal. It can be tailored for other Pascals by creating a file of
- reserved words and a file of built-in procedures for the particular
- compiler.
-
- Two versions of the PXREF are available - one for MSDOS, and one for
- OS/2 protected mode.
-
- RUNNING PXREF
-
- To run the program, enter PXREF. The complete syntax is:
-
- PXREF [infile] [listfile] [options]
-
- Infile is the Pascal file name. If this file name is not included on
- the command line, you will be asked for it and the listing file name.
- A file extension of .PAS is assumed if none is given.
-
- Listfile is the listing file name. To output to a printer, enter
- LPT1:, COM1:, etc. If the list file is omitted and the input file
- name is given, the input file name with the extension .LST is used for
- the list file.
-
- Options:
-
- /BUILTIN or /B - Output a list of built-in functions and procedures
- referenced in the program.
-
- /NOBUILTIN or /NB - Do NOT output a list of built-in functions and
- procedures referenced in the program. This is ordinarily the
- program default. It may be specified to override the default
- file.
-
- /RESERVED or /R - Output a list of reserved words referenced in the
- program.
-
- /NORESERVED or /NR - Do NOT output a list of reserved words referenced
- in the program. This is ordinarily the program default. It may
- be specified to override the default file.
-
- /LIST or /L - Output a program listing along with the cross reference
- listing.
-
- /NOLIST or /NL - Do NOT output a program listing. This is ordinarily
- the program default. It may be specified to override the default
- file.
-
- /UNREF - Output only those symbols with a single reference in the
- cross reference listing. This helps find unreferenced variables.
-
- /NOUNREF - Output all referenced symbols in the cross reference
- listing. This is ordinarily the program default. It may be
- specified to override the default file.
-
- /PRINT or /P - Output page headings and page feed characters in the
- listing if it is sent to a disk file. (The page headings and page
- feed characters are always output if the listing is sent to LPT1:,
- COM1:, etc.)
-
- /NOPRINT or /NP - Do NOT page headings and page feed characters in the
- listing if it is sent to a disk file. (The page headings and page
- feed characters are always output if the listing is sent to LPT1:,
- COM1:, etc.) This is ordinarily the program default. It may be
- specified to override the default file.
-
- /WIDE or /W - Use a line length of 132 columns.
-
- /NOWIDE or /NW - Use a line length of 80 columns. This is ordinarily
- the program default. It may be specified to override the default
- file.
-
- /MS - Source file is Microsoft Pascal.
-
- /TP - Source file is Turbo Pascal.
-
- /LL=nn - Specify the line length in columns. nn = number of columns.
- /LL=80 does the same thing as /NOWIDE. /LL=132 does the same
- thing as /WIDE.
-
- /PL=nn - Specify the page length in lines. nn = number of lines.
-
-
- THE DEFAULT FILE
-
- Program defaults may be specified in the file PXREF.DAT. To do this,
- edit the file and put any of the above parameters in the file. There
- can be more than one parameters on each line, and there can be more
- than one line of parameters.
-
- For example, to set up the program for Turbo Pascal and a wide
- carriage printer, you could put the following in the file PXREF.DAT:
-
- /TP
- /WIDE
-
-
-
- CUSTOMIZING PXREF
-
- PXREF uses two files - one containing lists of key words and another
- containing a list of built-in procedures. The is one set of these
- files for Microsoft Pascal and one set for Turbo Pascal:
-
- MSRESERV.DAT - Microsoft Pascal reserved words.
- MSBUILT.DAT - Microsoft Pascal built-in procedures and functions.
-
- TPRESERV.DAT - Turbo Pascal reserved words.
- TPBUILT.DAT - Turbo Pascal built-in procedures and functions.
-
- The files used depends on the /MS or /TP parameter in the default file
- or the command line. To configure this program for another Pascal
- compiler, change one set of the files to contain the appropriate
- symbols used by the new compiler.
-
-
-
- PROGRAM LIMITATIONS
-
- This program can handle a maximum of 3000 variables and 20000
- references. This is probably enough for any module that can be
- compiled by the Microsoft or the Turbo Pascal compilers.
