CP, Jerry, Shelly,
CICS eh! Am starting to feel at home:-) .. likely you know too what
copybooks are? I will think to your comments especially about the
'cics differences' and will bother you again shortly - sorry .
Graham
P.S. Have googled, bought a php video tutorial, still not clear on
'calls' so a side question if I may:
Being able to call a windows cmd file from my driver php pgm is a MUST
for my project (enormously larger than the student record system I
used as illustration) .. but I believe I can call a windows cmd file
from php and something like this is possible:
- block A of some php code
- 'call udogen.cmd aparm, bparm' (udogen contains many calls)
- block B of more php code e.g 'test return code'
i.e. after udogen.cmd has run control returns to block B with a return
code.
This would work?
