Why does such a language need to be provided by IBM?
Can a third-party vendor provide it?
- Dave Rivers -
It would be unreasonable for IBM to require a third-party product to
customize z/OS, or to expect IBM to help diagnose strange z/OS failures
caused by bad exits generated by some other vendor's product. z/OS
customization must be possible with what is included with z/OS. So
until IBM supplies alternative non-Assembler facilities for all exits
and customization, some Assembler expertise would seem to be a requirement.
Our application programmers are not that familiar with z-architecture,
much less Assembly Language; but those of us in mainframe Technical
Support certainly are. That knowledge is not just relevant to writing
Assembly code utilities and exits, but is also useful in understanding
why some approaches to application implementation in higher level
languages are inefficient, and useful in having the credibility to
communicate that to applications development. A management that thinks
it can do without any of that expertise in house is short-changing the
organization on multiple fronts.
And so you'll bring us in to teach Assembler to your applications programmers?
Great! The benefits will be amazing and the costs low.
