Answer Posted / rajesh reddy
The link() command is used to pass ctrl from an application
progrm at one logical to another application at the next
lower logical level.The calling program expects control to
be returned.
The xctl() command is used to pass control from one
application to another application program at the same
logical level .The calling program does not expect contol
to be returned.
In both cases data can be passed through a special purpose
register COMMAREA.
