There is. CBT file 939 includes a Rexx interface for TSO Rexx. From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On Behalf Of David Crayford Sent: Monday, January 13, 2025 9:53 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: Pipes
If only there were a Rexx PCRE2 command processor for TSO REXX. The challenge with regular expressions, especially in Perl, which is arguably one of the least maintainable programming languages, is how quickly they devolve into an unmanageable mess. PEG parsers, on the other hand, are far more structured than regex engines and are easier to comprehend since they can be broken down into components. For the Python enthusiasts, here’s a good PEG parser library: https://urldefense.com/v3/__https://github.com/erikrose/parsimonious__;!!Ebr-cpPeAnfNniQ8HSAI-g_K5b7VKg!OAQXVcJNwKIO2mBmhOVkR1oOAo8SCynp7xw2d9qDSqQF-K5_FT9PzlDaBnDwSpd0HPRn0KT3S6WFLUnFCLcihVZ9PWsSvlxO0hCmb0Tk$<https://urldefense.com/v3/__https:/github.com/erikrose/parsimonious__;!!Ebr-cpPeAnfNniQ8HSAI-g_K5b7VKg!OAQXVcJNwKIO2mBmhOVkR1oOAo8SCynp7xw2d9qDSqQF-K5_FT9PzlDaBnDwSpd0HPRn0KT3S6WFLUnFCLcihVZ9PWsSvlxO0hCmb0Tk$> On Tue, Jan 14, 2025 at 10:16 AM Seymour J Metz <sme...@gmu.edu<mailto:sme...@gmu.edu>> wrote: > PCRE2 has quite a bit more than ECMAscript. > > -- > From: IBM Mainframe Discussion List > <IBM-MAIN@LISTSERV.UA.EDU<mailto:IBM-MAIN@LISTSERV.UA.EDU>> on behalf > of David Crayford > <00000595a051454b-dmarc-requ...@listserv.ua.edu<mailto:00000595a051454b-dmarc-requ...@listserv.ua.edu>> > Sent: Monday, January 13, 2025 8:24 PM > To: IBM-MAIN@LISTSERV.UA.EDU<mailto:IBM-MAIN@LISTSERV.UA.EDU> > Subject: Re: Pipes > > External Message: Use Caution > > > There is already a package for REXX regular expressions.
