Parameters

label

   Specifies a label of 1 to 255 alphanumeric characters that
   appears as the first item on a command line. A label cannot
   contain embedded blanks. When the CALL command is executed,
   control passes to the command following the specified label.

   The label can precede or follow the CALL statement in the
   current command procedure. A label in a command procedure must
   be terminated with a colon (:).  Labels for subroutines must be
   unique.

   Labels declared in inner procedure levels are inaccessible from
   outer levels, as in the following example:

   $CALL B
   $A: SUBROUTINE
   $  B: SUBROUTINE
   $  ENDSUBROUTINE
   $ENDSUBROUTINE

   In this example, the label B in subroutine A is inaccessible from
   the outer procedure level.


parameter [...]

   Specifies from one to eight optional parameters to pass to the
   command procedure. Use quotation marks (" ")  to specify a null
   parameter. The parameters assign character string values to
   the symbols named P1, P2, and so on in the order of entry, to a
   maximum of eight. The symbols are local to the specified command
   procedure. Separate each parameter with one or more spaces.

   Setting bit 3 of DCL_CTLFLAGS to 1, specifies from one to
   sixteen optional parameters to pass to the command procedure.
   Use quotation marks (" ")  to specify a null parameter. The
   parameters assign character string values to the symbols named
   P1, P2, and so on in the order of entry, to a maximum of sixteen.
   The symbols are local to the specified command procedure.
   Separate each parameter with one or more spaces. If you clear
   the bit 3 of DCL_CTLFLAGS, the default parameters are set (that
   is, (P1, P2, . . . P8)).

   You can specify a parameter with a character string val
