i am makinga 4x4 keypad interacing program where da character pressed has to be sent serially to anothr board.. checking all 4 coulumns for each row, i gave a an exit command
jb col4 exit
where da exit subroutine was written at da end fisrt it gave me an error (TARGET OUT OF REACH) THEN, realizing jb doesnt hav long enough range, i changed it to
jb col4 JUMP JUMP: acall exit
now its giving an error "UNDEFINED SYMBOL (PASS 2)
tell me what to do? i have to make it jump only if my "jb col4" condition is fulfilled
i know about the comma and i know about the jump/call differnce
And you blissfully hid that knowledge under the carpet .... why?
if u have the answer to the real question,
You have made it both impossible and undesirable for anyone to actually give you that answer.
Undesirable by stubbornly insisting on childish SMS language despite having it pointed out as inappropriate.
Impossible by stubbornly refusing to supply any useful information, despite being called out on that, too.
i know i can program in assembly
No. You only believe so, and that belief is clearly wrong. And the very facts that a) you had to ask this question in the first place, b) are unable to state the question in a usable fashion, and c) can't be bothered with the required level of precision of expressing yourself, prove that.
