/*
 * protos.h - ANSI-style function prototypes for Pcal sources
 *
 * Revision history:
 *
 *	4.3	AWR	12/06/91	added more routines
 *
 *	4.2	AWR	10/03/91	added various routines newly
 *					incorporated into writefil.c
 *					and pcalutil.c
 *
 *	4.02	AWR	06/07/91	added find_executable()
 *
 *	4.0	AWR	03/01/91	use <stdlib.h> where possible
 *
 *		AWR	02/19/91	adapted from Bill Hogsett's source
