Call statement can be said to be similar to LINK since both
transfer control at Lower logical Level whereas XCTL
transfers control at the same level. Also in CALL the
control must transfer to the calling program like LINK but
unlike XCTL. In CICS, information is passed to the called
pgm through DFHCOMMAREA alongwith lenght of data. XCTL
command requires fewer overheads, hence its performance is
relatively better in comparison to the LINK command. Also,
the calling program does not expect control to be returned.
