Task 1 - Defining the Function Header 

The function you are about to create is executed on completion of data
entry for the product_no field on the product_scrn data screen.  The
function reads the product file using the value just entered as the key
for the file search, and then displays the data from the file if a
matching record is found.  For HP ALLBASE/SQL based applications, the
function initially calls an SQL logic block to declare and open a cursor
on a matching record, if it is found.

To access the function header screen: 

   1.  From the main menu, select the Logic option.

   2.  Select Functions.

   3.  Choose Header.
