Anyone,

I am in need of some assistance with RPG/IV pointers. My problem is 
this.. I have created a procedure that accepts parameters. This 
procedure will fetch a record in a file by key. This file contains
3 fields of 256 bytes (Flat file structure). After finding the
record I asked for, I need to load that field data into a Data Structure 
in my main program. The data structure breaks out all of the fields
for me. The problem is that depending upon what record I fetch from
a file points to a different data structure. 

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 only other choice is to pass back
the data in a field and have the main program move it into a data 
structure, but I would prefer to have my procedure do it.

Thanks in advance,

Michael
