XtrPRN by JJO

     PURPOSE

     XtrPRN may be invoked from the DOS prompt or from within a batch
     file (see below) to extract and print subroutine calls and comments
     (optional) from Turbo Pascal source files.

     If no printer options are selected, XtrPRN defaults to Epson and
     should be compatible with most printers.

     USAGE

     Syntax: XTRPRN [?] <filespec> [options]

     Parameters: [] optional and <> required, where a parameter is a
     character or a string (no spaces). Parameter sets must be separated
     by one or more spaces where so shown above.

                              Parameter List

     ? means display this file (/? is also acceptable).

     Filespec is the target file (and its path); e. g: c:\Pascal\Test.Pas.

     Options, one or more of (any order and case);
        /B    forces black & white display.
        /C    centers header and date.
        /D    inserts date after header.
        /H:c  sets header style (c = (S)tandard, (H)igh or (W)ide).
        /L:n  sets line spacing (n = 6, 4 or 8 lpi).
        /M:n  sets margin (n = 0..10).
        /N    insert page numbers.
        /P:n  chooses printer port (n = 1..2).
        /Q:c  sets print quality (c = (D)raft, (E)mphasized or (L)etter).
        /T:c  sets type style (c = (P)ica, (E)lite or (C)ompressed).
        /U:c  selects printer (c = (E)pson, (D)ataproducts or (I)BM).
        /V    include compiler directives and comments.
              The defaults are listed first.
              If H, L, Q or T are specified for other than an Epson (or
                 clone), then enter a printer code.

     NOTES

     If there are command line errors or the specified target file and/or
     printer is/are unavailable, XtrPRN halts with an error message.
     Error messages are beeped and left on the screen when XtrPRN
     terminates.

     If a header style is specified, it only affects printing of the
     file name (header). If centering is specified, only the header and
     date are centered.

     This file may be printed via MerPRN or by typing at the DOS prompt
     TYPE XTRPRN.TXT > PRN.


     BATCH FILE USAGE

     XtrPRN is designed for execution from within a batch file. When so
     used, test for an error code returned by XtrPRN and, if found, stop
     batch execution until the problem is cleared. This can be done by
     inserting a line like this after each call to XtrPRN:

                          IF ERRORLEVEL 1 GOTO Error

     where "Error" can be any line(s) which cause the batch process to
     terminate. See the sample batch file XtrEx.Bat.
