INSUBCONTINENT EXCLUSIVE:
It the 1980s, and legacy systems are already a problem
IBM is still shipping source code for big-iron internals, says this mainframe pilot fish.&IBM discontinued supporting BTAM under CICS, but
we had a major customer who communicated via CICS BTAM,& fish says.Translation: The big customer uses the CICS transaction-processing
system, and connects to it over telecommunication lines using the very old BTAM protocol — and IBM has just stopped supporting that
approach.Boss instructs fish to put BTAM support back in — after all, she does have access to the source code
Fish thinks that a bad plan, since changing internal mainframe system code is never a good idea.
