RE: V5R1 Library List Enhancement (was: PRTCMDUSG RTVJOBA)

[Evan Harris <spanner@xxxxxxxxxx>]

I wonder whether you won't have to recompile unless there's something I
missed in the original post(s)

I would have thought RTVJOBA would choke on the fact that it is trying to
retrieve a 2500 character parameter  and that size doesn't match the
field size you are placing into it. 

What happens if (just for arguments sake) you code a RTVJOBA that puts
the LIBL variable into a variable with only 150 characters because you
only need the first 15. My recollection is it won't compile because the
reciever variable size is incorrectc.

Since in this case the program will be lready compiled my expectation
would have been a run time error.

Having said that I don't see it as a huge big deal - most of my LIBL
stuff is dealt with through one or two standard functions. It's some
work, but ... given the goodies rumoured to be in this release, I'll wear
that happily. 

I think the extension to the number of libraries may be a good thing as
it may enable more libraries to be more modularly aligned with their
purpose, but like all good things it could perhaps be used "for evil
instead of niceness"....
