I've just announced in the C/C++ forum the availability of PCRE for z/OS 8.33 V2, but the real audience that should use this package is you, the COBOL programmers.
PCRE is a library that provides Perl Compatible Regular Expressions. This port allows all LE languages (COBOL, PL/I) to use regular expressions Perl style. This is a powerful and useful functionality.
The original library and the port are both Open Source and are published under the BSD license.
