Using Pointers

[Jon.Paris@xxxxxxxxxx]

 >> I thought that I could use a pointer to point to a data structure and
pass that to my procedure and have the fields read in moved to that
pointer. My problem is that I don't uderstand how to use RPG/IV pointers
that well and am really confused.

My approach would be to have the procedure read the file and pass back a
pointer to the whole record.  Simple enough to do if you use the record
format as an extern described DS in the program.  Then in the calling
program you use a set of BASED DS - one for each of the formats of data
retrieved.

In the sample I sent Michael, I use a program described file but that was
only because I'm having to develop the routines on the road while I have no
access to a "real" AS/400.  By using a program described file I can at
least get Code/400 to verify that I have no syntax/semantic errors in the
code even if I can't test it.

If anyone else wants the sample code please e-mail directly to me - please
don't put requests on the list as I haven't always got time to read it !!
