Re: declaring a file local to a sub-procedure

I don't think so Rob. This is new in 6.1

Files passed as parameters
A prototyped parameter can be defined as a File parameter using the
LIKEFILE keyword. Any file related through the same LIKEFILE
definition may be passed as a parameter to the procedure. Within the
called procedure or program, all supported operations can be done on
the file; I/O can only be done through data structures.

If they are the same format id then that's been support for quite awhile.

Yes, as discussed a lot of times, being able to pass the file would be
hugely beneficial to "simplify" a lot of code.  Anybody heard anything
about this being supported any time in the near future?

Nope - nothing special.  Which is why using STATIC for the file is
probably a good idea if the recursive capabilities are not needed.

In many cases I think the ability to pass a file in as a parm to a
subprocedure or program will be more useful for generic routines than
being able to have the file local to the subproc.

This now brings up an additional question, since this works along
the same
way as a USROPN, how much additional overhead does this generate?  I
mean,
if you include a file locally to a procedure and that procedure is
invoked
for every order, the overhead for opening and closing that file
could be
huge.....

Or does IBM preload the file so the overhead is lower on subsequent
opens?
