- When I worked as an MVS/JES2 or CICS systems programmer I usually
- "modified" them by writing exits. I believe that such modifications
- would qualify as systems programming (even though one is not directly
- modifying vendor supplied code) since the exits usually change the way
- the vendor supplied system behaves. While I haven't done this kind of
- stuff on a mainframe for the last 10 years I bvelieve that it is still
- a common practice to do this in most installations. Therefore, it seems
- like each installation would need a systems programmer on staff to create
- and maintain such exits.
-
- NOTE: I stopped doing this stuff because the shop I was in began
- giving us smaller and smaller testing windows (for example - 2AM Sat.
- nite for 2 hours). Since system modifications affected everyone and
- testing required standalone use of the system it just became too much
- of a hassle to debug a change and install it in a reasonable amount
- of time (1-2 months).
