In fact, it does more than simply show the products, this program is use
to select the product in an order entry application. Also the user can
request to see the product file by positioning on a line and pressing a
function key. For those reason, i can not use the "raw" runqry aproach.
(also, the users would not apreciate the runqry screen and ask me to
change it which i could not do).
