Call is for static call to the sub module. The load module
of main module will contain the load of called sub module.
So you need to generate the main module if you happened to
do any change in the sub module otherwise it won't pick up
the correct load.
while
Link is the dynamic call to the sub module. At the run time
the linker will link the sub module load. So no need to
generate main module if you happened to change sub module.
Any more info required????

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.
