Why use SWAPF STATUS,W ? I can see that if STATUS happens to be 0, the Z
flag would be set but that would happen AFTER the current status was saved
in TEMP_Stat, wouldn't it? Is there another reason?
>And does anyone have any other suggestion and/or ideas for multitasking and
reenterant code? I like the examples given, but have trouble getting my
routines to cooperate adapting it to the interrupt and single timer on a 16C84.
