I don't know why there is several types of jump and call... Speed of execution?..... Efficiency ? but we have SJMP, LJMP and AJMP

SJMP must be the quickest 128 bytes down and 127 bytes up.

Now calls are different! The difference between ACALL and LCALL.... Well there's not really much difference...Most chips only have 2k memory and both calls can cope.

The same can be said of AJMP and LJMP.... maybe its for chips that break the 2k barrier?

Thank you very much, Rogers.

Could you please tell me what a "monitor program" is in the context of a MCU? Thanks. Right now I'm too lazy to take a new clearer scan!

a monitor program is used to test the microcontroller to make sure that it is functioning properly. if it runs successfully then microcontroller is ready to be used for further programming.
