You can easily write a script to implement your own version of EDIT CHANGE. ISPF has been functionally stabilized and is effectively on life support. I would not expect any new features. Like it or not, IBM is investing in new technologies that run in shell environments. What advantages does my package have over the PCRE2 REXX implementation on the CBT tape? I recently evaluated that version because Ze’ev Atlas is planning to discontinue support. Unfortunately, the REXX external function performs a STORAGE OBTAIN on every call, and the additional linkage overhead could become a performance issue. The PCRE2 maintainer recently asked for feedback on Discord whether to continue supporting EBCDIC. I worked with him and helped fix several testing issues: https://github.com/PCRE2Project/pcre2/commit/0d0ac3aa0fe2c91dc648f809a7aac78ebc57048b The z/OS PCRE2 code is beginning to decay. Ze’ev is not familiar with building software in z/OS UNIX and does not use Git. As a result, he copied the entire PCRE2 code base into PDS data sets and builds it using JCL. That makes it very difficult to apply upstream fixes or track new releases. I uploaded the contents of the CBT tape to GitHub. If anybody is interested in PCRE2 from COBOL or REXX then I encourage you to pick up from Ze’ev. He was soliciting for somebody to take the reins. https://github.com/daveyc/PCRE2-z-OS > > -- > Shmuel (Seymour J.)
