**********************************************************************
* HISTORY
* $Log: vmnlist.c,v $
* Revision 1.3 90/12/11 18:00:24 mja
* Add copyright/disclaimer for distribution.
*
* 06-Nov-87 Glenn Marcy (gm0w) at Carnegie-Mellon University
* Moved location of vmnlist file.
*
* 06-Dec-85 Glenn Marcy (gm0w) at Carnegie-Mellon University
* Added code to return as soon as all symbols have been found.
*
* 26-Nov-85 Glenn Marcy (gm0w) at Carnegie-Mellon University
* One more try... When we initialize the nlist array, place the
* number of entries into a counter. Subtract one from the counter
* every time that we find a symbol that we are looking for. If we
* didn't find a symbol the counter will be positive and we should
* indicate that nlist should be called.
*
* 06-Nov-85 Glenn Marcy (gm0w) at Carnegie-Mellon University
* Fixed incorrect terminating condition check.
*
* 05-Nov-85 Rudy Nedved (ern) at Carnegie-Mellon University
* Created.
