:ROUTINE

This routine name can be used in GOTO or CALL requests which are the two function statements that transfer control to a routine name.

Note: Do not include the colon in a GOTO or CALL function that references the routine name.

The format of this function is :routine_name. The colon (:) in column 1 defines a routine name, and must be followed by one or more characters that make up the routine name. For example, :SENDFILE.
