re: http://www.garlic.com/~lynn/2013o.html#25 GUI vs 3270 Re: MVS Quick Reference, was: LookAT
this is quick&dirty conversion of internal (cms) ios3270 "green card" to html ... trying to preserve a little of the original look&feel http://www.garlic.com/~lynn/gcard.html very early in rex(x) days (before it had been release as product), I wanted to demo that rexx wasn't just another pretty scripting language. I chose to re-implement IPCS (very large application, at the time implemented in assembler) in rexx with objective 1) have ten times the function, 2) have ten times the performance (interesting going from assembler to interpreted rexx) and 3) take less than half-time over 3 months elapsed. some past posts http://www.garlic.com/~lynn/submain.html#dumprx I finished early ... so started a library of automated scripts that would search/recognize a variety of failure signatures. I had assumed that it would be released to customers in place of the existing IPCS. However, even though it was used by nearly every customer support PSR and internal datacenter, it wasn't shipped to customers. However, I did manage to get approval to give SHARE presentation on the implementation details ... and within a very short time, similar implementations started appearing. One of the things I did for DUMPRX was obtain the softcopy GML for system messages & codes manual ... and massage it into an online form. DUMPRX ran either as line-mode (terminal) exec ... or within XEDIT as a session macro (with all input/output sesssion preserved as XEDIT file). note ios3270 was what was used for the service panels on the 3090 service processor (3092) ... which was really a pair of 4361s (for redundancy and availability) running a customized version of vm370/cms release 6. The pair of 3370s FBA required for every 3090 (even purely MVS accounts that didn't have FBA support) ... were required for the 3092 vm370/cms systems. a couple of old email references: http://www.garlic.com/~lynn/2010e.html#email861031 http://www.garlic.com/~lynn/2010e.html#email861223 -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
