EFS program context area

The EFS program context area is a private communication area that can be set up and used by the EFS program as appropriate. DFSORT sends the context area address to the EFS program at each Major Call and at each call to EFS01 and EFS02.

The EFS program is responsible for obtaining (at Major Call 1) and releasing (at Major Call 5) the necessary storage for the EFS program context area.
