/if, /define, binder language

["Richard B Baird" <rbaird@xxxxxxxxxxxxxxxxxxxxx>]

Bob,

I'm a little fuzzy on the /IF and /DEFINE declarations.

I remember seeing them discussed before, and I think they have something to
do with optionally defining portions of a copybook to your program......

am i right?  what does it buy you other than the memory needed to define
these specific specs?

by defining all prototypes of a SP to your program, does it bind all
functions from the SP even if you don't use them?

in otherwords, if you have 20 functions in a service program with an
associated prototype copybook, and you include the entire copybook in your
main module, does it bind all functions to the program?  and conversely
only including the prototypes of the functions you actually use cause only
those functions to be bound to the program?

or not?  ;)

thanks,

Rick
