Also note it you want better performance, consider using the C Library
function, memmove directly from RPG. Serach the archives for more
info.

***NOTE: do not use memcpy as your source and destinations will be
overlapping which is not supported by memcpy. But is supported by
memmove.

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.
