Early in the days of REX (before rename to REXX and release to customers), I wanted to demonstrated REX was not just another pretty scripting language so I chose as demonstration to rewrite IPCS (dump reader, huge amount of assembler code) in less than 3months elapsed time working less than half time would have ten times the function and run ten times faster (some tricky coding to make interpreted rex run ten times faster than assembler). I finished early, so developed a set of automated library routines that would examine for the most common types of failures. I thot that it would then be released to customers as upgrade to existing IPCS, but for some reason that never happened .... even tho it came to be in use by nearly every internal datacenter and customer PSR. I eventually got permission to make presentations on DUMPRX and how it was implemented ... and within several months, similar implementations started appearing at customers. Eventually the 3092 service process group contacted me about including it in 3092 release. Since their vm370/cms release 6 was heavily modified and out-of-date, they had to do almost all the service themselves and they relied heavily on DUMPRX. some old email from the 3092 group http://www.garlic.com/~lynn/2010e.html#email861031 http://www.garlic.com/~lynn/2010e.html#email861223 past posts mentioning dumprx http://www.garlic.com/~lynn/submain.html#dumprx -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
