MATCH Function

Use the MATCH function to determine if a DSN matches a pattern mask.

A return code of zero indicates that the DSN matches the pattern.

A return code of four means the DSN does not match the pattern.

Higher return codes indicate an error.

Non-zero return codes are accompanied by a 24-character error message.
