 		 #98863 - no RTOS
Responding to: ???'s previous message
hi,

Erik Malund said:

A_SUBROUTINE:
CALL SAVE_CONTEXT
; a task
CALL RESTORE_CONTEXT

why is one called a subroutine and another a "task" ? If this is some URTOS thingy, that should be stated.


No RTOS there. "A task" just a place where I do some work (sorry for I named it "a task") which modifyes most registers. So to keep their values I call these two routines and place needed code between.

Regards,
Oleg
