PROCEDURE REFERENCE ARRAY Declaration

Placement of Procedure Reference Arrays
Example of a PROCEDURE REFERENCE ARRAY Declaration

The PROCEDURE REFERENCE ARRAY declaration declares a procedure reference array, which is a structure that allows a group of like procedures to be treated as a single entity. A procedure in the group can be invoked by referencing an element of the procedure reference array. An imported procedure reference array declaration is allowed only inside a connection block type.

<procedure reference array identifier>

An identifier that is associated with a procedure reference array in a PROCEDURE REFERENCE ARRAY declaration.
