Re: Need OCCURS when defining data structures

[Charles Wilt <charles.wilt@xxxxxxxxx>]

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.
