RE: Another Question / Stored procedure w/result set.

Tim:

Haven't tried this, but haven't seen other replies either, so, maybe like...

d presarray                       *
d resarray        ds                  based( presarray ) occurs(32767)
d   field1                       5  0
d   field2                      15
d   field3                       9  2

Then, when you know the value of i, alloc as much space as needed while 
referencing the presarray pointer. When finished, dealloc the space.

Shouldn't matter if your occurs() specifies the maximum since it shouldn't 
actually reserve the space. Just take care not to overstep your alloc'd area.
