Answer / santosh khot
Both are Tranfering control from one program to another
program where as link sends the control from one level to
another level and expect the control to be returned back
but XCTL does not expect the control should be returned
back.

Answer / jkb
The LINK command calls the sub rogram at the next lowest
logical level. The main program remains in memory. The
XCTL command transfers control to the sub program at the
same logical level. The main program is released from
memory.

Answer / cheran pogu
The LINK command is used to pass control from an
application program at one logical level to another
application at the next lower logical level. The calling
expects the control to be returned to it. the control is
returned at the next sentence when called program completes
execution.
The XCTL command is used to pass control from one
application program to another application program at the
same logical level.The calling program does not expect
control to be returned.Data can be passed to the program
less overhead,performance is relatively better in
comparison to the LINK command.XCTL does not establish
return mechanisam like link.

Answer / debashish bagg
If we XCTL to a program the calling program is removed from
main memory and called program is loaded on to the memory
while in LINK memory of the calling program is retained.
thus in a sence XCTL is pure Pseudoconversation while LINK
is a conversational program.

Answer / kumar
Link transfers the control to the lower logical levels and
expects the control back.
Whereas XCTL transfers the control to same logical level
and never expects the control back.

Answer / uma mahesh
XCTL doesn't returns the control to original position. LINK
returns the control to original postion. LINK is like
perform statement but it works from program to program.
