General command line to string or numeric variable reading

Modified for command line parsing for EPLD multi-fitter program

    Mike James 7 Feb 1996

 * $Log: cmdutil.c,v $

 * Revision 1.1.1.1  2003/11/04 23:34:56  mjames

 * Imported into local repositrory

 *

 * Revision 1.13  2002/09/09 10:26:56  mjames

 * Removed set generic range and replaced it with a set generic value command

 * that takes both integers and ranges.

 *

 * Revision 1.12  2002/08/14 11:56:13  mjames

 * Removed NT specific file opening , as recent Cygwin DLL does not

 * like the code I was using to protect NT from screwing up on opening

 * read-only files for write (it crashes as the first byte is written)

 *

 * Revision 1.11  2002/08/06 12:52:59  mjames

 * Merge in from latest version

 *

 *

Revision 1.12  2002/04/10 14:29:10  mjames

Moved setting debug level to cmdutil.c

Amended print external command to list all net names on socket pins

whether routed or not.

Revision 1.11  2002/03/21 17:14:15  mjames

Added search path to vertical file opening for read

Revision 1.10  2002/01/16 11:22:42  mjames

database.h header file is read in first as it undefined DLL stuff irrelevant

to HPUX

Revision 1.9  2001/12/13 22:14:25  mjames

Corrected nested command handlers to allow variable passing without corruption.

Revision 1.8  2001/11/19 10:41:52  mjames

Merged back DTC release

Revision 1.7.2.1  2001/11/16 15:08:13  mjames

Fixed incorrect printf specifier.

Added () barackets to conditional expressions

Revision 1.7  2001/10/31 22:20:01  mjames

Tidying up problematical comments caused by CVS

'intelligent' comment guessing

Revision 1.6  2001/08/31 08:19:18  mjames

Added stuff to prevent errors with "sys/stat.h"

Revision 1.5  2001/06/20 13:43:33  mjames

Corrected logical expression required to open a file : need user rights to open this file

either 'r' and read rights or 'w' and write rights in trap_fopen call.

Revision 1.4  2001/06/19 05:19:52  mjames

Created a trap_fopen to overcome trying to write to read only files.

If this attempted in NT the file can be opened but not written to.

Revision 1.3  2001/06/06 12:10:24  mjames

Move from HPUX

Revision 1.2  2001/02/06 22:41:15  mjames

Added correct argument passing for 'read file comp_suffix arg0 arg1 arg2 ...
