NLMATCH

Compares a string against a pattern which has previously been compiled with the NLMATCHINIT intrinsic.

   I                        BA         BA      IV

   result := NLMATCH(comp_pattern,string,length);

Zero is returned in result if the string matches the compiled comp_pattern. If there is no match, the mismatch location is returned.

result	Integer Error	Meaning
	1	NLS is not installed
	2	The specified language is not configured
	100+n	n is the mismatch location

comp_pattern

Byte array (required)

A byte array containing the compiled form of a comp_pattern as returned by NLMATCHINIT.

A pattern consists of a series of special characters that indicate the type of data to be selected. These characters are:

string

Byte array (required)

The string to be compared against the comp_pattern.

length

Integer by value (required)

Length, in bytes, of the string to be compared.
