Actually, Barbara gave you the better solution:  Code DIM on
the parameter definition.  Since you don't know how many elements
will be returned until run-time, code DIM(1) or OPTIONS(*VARSIZE)
on the parameter definition.

(I just tried something:  If you code a scalar parameter on a
call where the prototype expects a OPTIONS(*VARSIZE) array, the
compiler accepts it!)

Oh yeah, one more thing:  Since you expect values back from the
API, don't code CONST on that parameter.  It may well work today,
but it's not guaranteed.

Cheers!  Hans
