I just tried calling an execute SP thus:

select *
from calc_price(1,200);

and it generates no result set - it should return a scalar value. ( I tried
under WISQL, and my own SQL Profiler)

This statement runs fine, both in WISQL and my SQL Profiler:

execute procedure calc_price 1, 200;

The BDE based SQL Explorer wont accept the above statement and I tried similar
attempts with QuickDesk, and IB Workbench (based on IBO) and they didn't return
a value. IBAdmin got the right answer, based on FIB.

This is a tricky problem. Iterating through the two options is not really a
solution, but I can't think of a better one, for now.
