DirPRN by JJO

     PURPOSE

     DirPRN may be invoked from the DOS prompt or from within a batch
     file (see below) to secure disk or directory files listings, sort
     them (optional) and print them (always).

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

     USAGE

     Syntax: DIRPRN [?][pathspec] [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).

     Pathspec is the disk or directory to search; e. g: a:\ or c:\DOS.
        If pathspec is omitted, the current directory is used.

     Options, one or more of (any order and case);
        /B    forces black & white display.
        /C    centers header and date.
        /D    inserts date.
        /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).
        /S:c  sort criteria (c = (N)ame, (E)xtension, (D)ate or (S)ize).
        /S:pc p is optional prefix for c (p = (A)ll directory entries)
              where default (no prefix) is files, only.
        /T:c  sets text style (c = (P)ica, (E)lite or (C)ompressed).
        /U:c  selects printer (c = (E)pson, (D)ataproducts or (I)BM).
              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 printer is
     unavailable, DirPRN halts with an error message. Error messages are
     beeped and left on the screen when DirPRN terminates.

     If a header style is specified, it only affects printing of the
     directory 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 DIRPRN.TXT > PRN.


     BATCH FILE USAGE

     DirPRN is designed for execution from within a batch file. When so
     used, test for an error code returned by DirPRN 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 DirPRN:

                          IF ERRORLEVEL 1 GOTO Error

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