Answer : Explanation : - Use a COBOL II CALL statement to invoke a subprogram. This method is transparent to CICS, which sees only the one load module. - EXEC LINK is similar to a call; it invokes a separate CICS program and ends with a RETURN to the invoking program- 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.
