Depending upon how you want to use the array, you may be better served 
using a scratch file or a user space.

You can use ALLOC or the bindable CEE APIs.  The basic idea is to define 
your array with 32767 elements, based on a pointer.  You ALLOC storage out 
of the default heap and use that as the pointer to your array.  The RPG for 
ILE Programmer's Guide has a chapter on using the APIs for dynamic arrays.

The April 97 issue of News/400 has an article on dynamic arrays.
