str_regexp_compare

	status.i4.v = str_regexp_compare(string.i1a.r, match_pattern.i1a.r
					 [,use_extended.i4.v]

	This routine compares a null terminated ASCII character string
	to a regular expression pattern.

	string		null terminated comparison string
	match_pattern	null terminated match pattern  (If a value of NULL is
			passed for this argument, the last pattern established
			will be used.)
	[use_extended]	use extended regular expressions flag
			(TRUE -> use extended regular expressions,
			 FALSE -> don't use extended regular expressions
				  (default))

	This function returns status values as follows:

	CLIB_NOINIT		match pattern has not been established
	zero			the string matches the pattern
	otherwise		the string does not match the pattern

	This function requires the following include files:

	cbslib_h
