this info is For all of the PASCAL conference people:

to use the rotuines in this Program you need to do the following

{$I path.......\Progname.h}

{$I Path.......\Helpuser.PAS}

{$I path.......\CMDPARSE.PAS}

 progname.H is a copy of the CMDPARSE.H File which contains the specific

 settings For the Program you are writing .

 HELPUSER.PAS is a Program specific help routine which get called by

 the routie CHECKHELP in CMDPARSE.PAS if the CheckHelp Procedure is

 used in the main Program. crude but effective.

 CMDPARSE.PAS -- this File contains all of the parsing routines. I keep this

 File in my .....\TP\INCLUDE directory .

 I set up a sepearte directory below the tp directory For each Program

 and copy the Files Helpuser.Pas and cmdparse.h into it thusly each

 copy of these two Files is customized For the give application While

 the actual parsing routines are kept in the INCLUDED FileS directory.

 there's no need to modify CMDPARSE.PAS

 using the parser..

       ) in the CMDPARSE.H File there are templates For all of the Array

 initializations. the switches to search For are manually inserted in to

 each Array item. additionally the Array sizes must be set where indicated

 in the CMDPARSE.H File.

       ) if you intend to use the routines in HELPUSER.PAS or to perform

a Filename validation  -- there is a template at the beginning of CMDPARSE.H

with Certain Constants which must be set.

      ) To call the Various routines in  the CMDPARSE.PAS File there are

Templates which you can cut and paste into you Program from  CMDPARSE.H

{--------------------------------------------------------------------------}

{                            NoCase,                                       }

{                             Var  CmdArray : CommandLineArrayType;        }

{                             Var  ResultNumber: Word);                    }

{                                                                          }

{--------------------------------------------------------------------------}

      ) To test whether an ON/OFF switch is present (such as /?) on the

commandline  use the following:

             if CmdArray.Switches.Present[number] then

                begin

                end;

      ) to get the argument from a switch .

            if CmdArray.ArgDsw.Present[number] then

               WhatEverVariable := CmdArray.ArgDsw.Arg[number];

      ) the Procedure ConvertArgtoNumber is avail to convert a

String on the command line to a decimal number.. this is only good for

for whole numbers w/o nnn. etc.

hope this stuff is useful -- there are other notes and comments sprinkled

throughout so please check those before calling..

finally - in the interest traversing the command tail only once the most

henious of Programming Constructs -- the Goto statement -- has been used.

please forgive me in advance....

questions comments and suggestions are welcome..

see the address in the CMDPASE.DOC File..
