RE: Memory being reused by %alloc on second call to program.

I agree, and I almost sent my own correction, Scott. Thanks. I did know
that, but was so caught up in the "problem at hand..."

This code is dangerous, because the final time through the loop, pDS
will be beyond the end of the allocation.

That's dangerous, because under some circumstances, OS/400 will send an
*ESCAPE message to your program when you set a pointer beyond the end
of
a space.

A better solution:

start = %Alloc(%Size(myDS) * NBR_OF_ENTRIES)
For I = 1 to NBR_OF_ENTRIES
pDS = start + (I-1) * %size(myDS);
Clear myDS
endfor
