Each of the functions in the \fIparseargs\fP library will set the external
character string \fIProgName\fP to be the name of the last command that
was operated upon by any of the library routines.
.PP
When an argument-descriptor array is first encountered by any of the
parseargs library routines, it is initially compiled into an intermediate
form that is more convenient to manipulate. As a direct result, it is not
advisable to attempt to index directly into the array to manipulate one
of the argument descriptors (because the argdesc that you thought was there
may actually be somewhere else). After the array has been given its initial
value(s), only \fIparsecntl\fP(3) should be used to manipulate or query the
attributes of an argument descriptor.

** ^FILE: patchlevel.h - current patchlevel for parseargs
**
** ^HISTORY:
**    04/10/91    Brad Appleton    <[e-mail]>
**    Patch04
**    - fixed problem with prompting in xparse.c:prompt_user()
**    - under vms, getenv was defined to be 'getsymbol', it should be
**      'get_symbol' (note the underscore).
**    - now uses <errno.h>
**    - parseargs no longer included <fcntl.h>
**    - fix bug in vms_args.c printing '[]' for required args and vis-a-vis
**    - fixed bug in argInput and argOutput in argtype.c
**    - fixed bug in <os>_args.c where ARGVALGIVEN was improperly being
**      cleared if the argument was a list or a vector. This was causing
**      parseargs(1) to screw up on optional lists.
**    - fixed bug in strfuncs.c:strnicmp()
**    - changed strfuncs.[ch] so that my version of strdup is always used
**      (my version dies if malloc failed, others return NULL).
**    - Added some changes for SUN and VAX
**    - Added -1 option to parseargs(1)
**    - Unhid the -# option to parseargs(1)
**    - More documentation fixes
**
**    04/04/91    Brad Appleton    <[e-mail]>
**    Patch04 (continued)
**    - fixed bug in xparse.c with PARSECNTL='Prompt' being ignored.
**    - added test.pl to test.all and added options to test.all
**    - fixed newline printing error in perl-scripts for parseargs(1)
**    - added -C option to parseargs(1) and to the docs
**    - added "patchlevel.h" to distribution
**    - added "what" string with version and patch level for parseargs(1)
**    - added hidden -# option to parseargs(1)
**    - add "doc/effects.inc" to distribution
**    - fix docs
**    - fix test.rc for Plan 9 shell
**    - fix parseargs(1) quoting for perl
**
**    03/22/91    Brad Appleton    <[e-mail]>
**    Patch03
**    - ascii docs fix
**
**    03/21/91    Brad Appleton    <[e-mail]>
**    Patch02
**    - documentation fix
