Explain the difference among the EXEC LINK, EXEC XCTL and
Cobol II static call statements in CICS.

Answer / guest
use a COBOL II CALL statement to invoke a subprogram. This
method is transparent to CICS, which sees only the one load
module. 2). an EXEC LINK is similar to a call; it invokes
a separate CICS program and ends with a RETURN to the
invoking program. or 3). an EXEC XCTL which transfers
control to another CICS program and does not get control
back.
COBOL II allows for static calls which are more efficient
than the LINK instruction which establishes a new run-unit.

Answer / shivanadri
In the COBOL it is control management.means the Operating
System pass the control from calling program to called
program in the same in two cases(LINK and XCTL)but the
difference is the control can come back when we use in the
case of LINK from called program to calling program when
completion of execution of called program. coming to the
XCTL the control never come back to the calling program from
called program
