James,

On the D specs, you can define a multiple occurring data structure using the OCCURS keyword.

Then in the calcs, you use the OCCUR operation code or %OCCUR function to refer to the occurrence you require.

Subject: Need OCCURS when defining data structures


I'm on a V5R2 machine and rewriting a program that currently uses 60 element
arrays when processing records. As part of the processing I have to move
element 59 to element 60, 58 to 59, etc and put the newly read record in
element 1. A friend (thanks Marshall) suggested that instead of using
arrays, define the arrays as data structures and move the data structure
instead. This should be much faster. But do I have to define each element
as part of the larger data structure? I guess there's no "OCCURS X TIMES"
in RPG, eh?

TIA.
