Actually, no.  You mean a per-process open file limit?
You could check the Makefile for any compile parameters
that the config may not show you.

...and keep them all concurrently open?
No offense, but TCL holding open 2000 files doesn't sound like a
very good way of doing things.  You have to have _concurrent_ access?

Yes the concurrent opens are necessary because the program attempts to do
the following
command up to 1000 times which opens 2 PPPD processes (master and slave)
each time--

	set pidnum [exec /usr/sbin/pppd notty noccp +ua $passwd_file <@
$sktClnt1 >@ $sktClnt1 &]

I changed the kernel Unix98 PTY limit from the default of 256 to 2048, 
but even the 256 limit is unobtainable with the file-max limit.  In the
RedHat-Devel-List archive, someone said that maximum open files is
configurable in /proc/sys.  Could something like /proc/sys/fs/file-max
be changed?  Since it doesn't help to exit the program and try to run
it again for just 2 more batch processes, it doesn't seem like I am
running into a "per-process" limit.
