Creating the procedure head

The procedure head consists of the SET-PROCEDURE-OPTIONS command, which is used to define the attributes of the procedure, and the DECLARE-PARAMETER block, in which the procedure parameters are declared.

The procedure head is always located at the beginning of the procedure. When a procedure call is issued, the commands contained in the procedure head are executed first, thus setting the procedure attributes before the commands in the procedure body are analyzed and processed (see chapter “Calling and controlling procedures”).

The following paragraphs describe how the procedure parameters are set and which standard attributes can be used. This is followed by an explanation of how procedure parameters are declared.
