udc's -- user defined commands -- have been around since nearly the dawn of
time ;-)
in the old (mpe v (5)) days they were (about?) the only way to write a
'script'...and calling a udc a script is probably a stretch. I guess you
could think of a udc more like an on-line job or simply a collection of
commands/programs to run.
with new mpe came true ci scripting and a whole host of specialized
functions that makes mpe scripting a real pleasure. (thank you, jeff!)
ido (in donna's opinion (hehehe)) there's only two reasons now to use a udc
-- when you need something to happen a login time ('option logon' will be
the 2nd line in the udc) and if you need to 'commandeer' an existing mpe
command (like listf or purge...or my personal fav -- shutdown). continuing
with donna's opinion....if I *have* to write a udc I'll bail out of the udc
by the 3rd line -- which will be an 'xeq' of a ci script.
as paul has discovered try to change a udc which is in use is a pain.
scripts are our friend.
...and sysstart is it's own animal ;-) - d
