IBM have recognized that 99% of users are computer illiterate, but have
99% of the money. So they are following Microsoft's 'lead' and,
step-by-step, implementing Windoze for mainframes. Other vendors are
just following suit. But the remaining 1% of users (with 1% of the
money) can still figure out how to avoid becoming panel-filling typists.
Thanks for the info. Great stuff. Cheers, Chris Poncelet

Anyone who writes Clist/REXX that invokes panels in batch doesn't have a clue
about what he/she/it is doing.
The company I worked for had a vendor product (Endevor) that performed various
functions using ISPF panels. Management wanted some of the functions to be
executed in batch, so I customized the panels to recognize a parameter that
would only be passed in batch. When the panel was invoked with the parameter it
filled in various fields automatically and simulated ENTER being pressed, which
invoked the next panel (and so on). Some of these processes went quite a few
panels deep and the whole thing worked flawlessly.

Gosh.
The ISPPLIB DD must be allocated in the JCL.
No; a dynamic allocation before ISPSTART will work just as well.
There are contrary valid points of view here:
o Not to require the programmer to provide resources he doesn't
intend to use.
o To require the programmer to supply in advance all resources
he might potentially use, in order to preclude a failure later in
the process.
ISPF apparently elects the latter; many programs elect the former
e.g. with respect to SYSLIB DD. Fortunately, ISPF doesn't require
that a display be available when the programmer intends not to
use one.
