One can not declare/create GDA in an external subroutine,
instaed it can use the GDA that is present in main calling
program.

Subprograms even don't have access to GDA. As they only need
the parameter data area to communicate with the calling program.

If a module of type program(P1) is calling another module of
Program(P2) using Fetch return then P2(the called program
module) can't have GDA defined in it.
But with fetch both can have GDA variables.
