An external subroutine can access the global data area used
by the invoking object(Program, Subprogram)
Moreover, parameters can be passed with the PERFORM
statement from the invoking object to the external
subroutine. These parameters must be defined either in the
DEFINE DATA PARAMETER statement of the subroutine, or in a
parameter data area used by the subroutine. Programs,
Subprograms and Subroutines Programming Guide
In addition, an external subroutine can have its local data
area, in which the fields that are to be used only within
the subroutine are defined.
However, an external subroutine cannot have its own global
data area.
