RE: array handling

[rob@xxxxxxxxx]

Just to beat a dead horse to death - you might be interested in overlaying
arrays.  Sample below:
     D                 ds
     D MyArray                        4a   dim(20)
     D  Code1                         2a   overlay(MyArray)
     D  Code2                         2a   overlay(MyArray:*next)

     D X               s             10i 0

      /free
       Code1(1)='AA';
       Code1(2)='BB';
       Code1(3)='CC';
       Code2(1)='ZZ';
       Code2(2)='YY';
       Code2(3)='XX';
       // At this time MyArray(1)='AAZZ', (2)='BBYY', (3)='CCXX'
       for x=4 to %elem(MyArray);
        Code1(x)=*hival;
        Code2(x)=*hival;
       EndFor;
       sorta code2;
       // At this time MyArray(1)='CCXX', (2)='BBYY', (3)='AAZZ'
       sorta code1;
       // At this time MyArray(1)='AAZZ', (2)='BBYY', (3)='CCXX'
       *inlr=*on;
       return;
      /End-free

This allows you to sort an array by a substring.  I think it is pretty
cool.  It is also great for related arrays - which sounds like what you are
doing.

It is RPGIV.  Just to clarify a bit, I am reading a
file (doing a reade) that contains MHS hold codes and
the corresponding legacy hold code.  I am then wanting
to load the array and later in the program I want to
do a lookup on the MHS hold code to find the
corresponding legacy hold code.
