Re: Multi Dimensional Array

Hmmm... in which version of RPG?

In RPG IV, the %subst() BIF allows you to access/change the areas
within a character variable without the need for a second dimension
on your array.

c                   eval      A = %subst(Array(X): Y: 1)
   or
c                   eval      %subst(Array(X): Y: 1) = A


Otherwise, simulating a two dimensional array isnt very difficult,
either.  In your example, you wanted an two dimentional character
array, 100 x 60.  So you can code it like this (and the same concept
should also work in RPG III)

D Array           S              1A   DIM(6000)

c                   eval      Array(((X-1)*60) + Y) = A
   or
c                   eval      A = Array(((X-1)*60) + Y) = A


(or, if you're still using RPG III)

E                    ARR      6000  1
 *
C           X         SUB  1         I
C                     MULT 60        I
C                     ADD  Y         I
C                     MOVE A         ARR,I
C                     MOVE ARR,I     A

Make sense?
