Re: How do I retrieve the RRN of a PF or LF in a RPG program.

George, you may be confusing digits vs. bytes.

As Bruce pointed out a 4-byte integer variable equates to 10-digits. The 
following example shows three ways of defining exactly the same thing.

====================
        Dcl-DS MyStr1;
          Variable1   Int(10);
        End-DS;

     D MyStr2          DS
     D   Variable2             1      4I 0

     D MyStr3          DS
     D   Variable3                   10I 0

====================
(The from/to notation for Data Structures is for byte positions. The 
length notation is for digits.) Apologies if you're already familiar 
with this; from the RPG IV Ref:

The length of an integer field is defined in terms of number of digits; 
it can be 3, 5, 10, or 20 digits long.
A 3-digit field takes up 1 byte of storage; a 5-digit field takes up 2 
bytes of storage; a 10-digit field takes
up 4 bytes; a 20-digit field takes up 8 bytes. The range of values 
allowed for an integer field depends on
its length.

HTH,
Brian.
