This is in addition to the above answers.
XCTL:-Copy of the data is passed to the called program. it
means data changed by called program will not reflect in
calling program.
Since it do not expect the control to return to calling
program, as soon as the calling program issues a XCTL
command, calling program will be released from memory and
called program will load into memory.
Link:-Data is passed to the called program. it means data
changed by called program will reflect in calling program.
It expect the control to return to calling program, called
program will not release from memory.
