error during build.
help needed.

In my view, RLF is an older command. cuz when i write in MPLAB it color does't change in blue.
 
You need to supply more information. Try posting all your code and explaining exactly what you are trying to do. Posting random questions is just wasting everone's time.

Mike.
P.S. this is starting to remind me of Walter.
 
Plz explain this, u write it in ur previous pose on page 1 of this thread.
how a carry will be gernate
 
Please study the data sheet and the above code until you understand how it works.

Mike.

This is the code.
It's one part voltage calculation is completed.
Other parts remaing( temperature measurement, frequency measure ment etc)
my orignal picture is not like this, my orignal picture is different from it.
I will share it later cuz that is in not completed yet.

You have told MPLAB that you are using a p18F452 and you have code for a 16F877A. Change the processor type to 16F877A under the "configure/select device" menu.

Mike.
 
After changing the processor errors remain =1
 
Have you tried reading what they say?, there is one error there, and sixteen identical warnings - for a start I would suggest you cure the cause of the warnings, and add the destination bit to the sixteen lines where you've left it off! - the default (file) may not be what you want, and it's bad programming practice not to include it.

The actual error is simple as well - do you know the difference between '0' and 'O'? - the assembler does!.
 
aLL PROBLEM HAS BEEN SOLVED
but now only one problem
MPLAB SIM not running
CORE-E0002: Stack under flow error occurred from instruction at 0x00002f

what is it's meaning???
 
Program execution starts at location zero. You do not have any code at the start location. Looking through your code, you don't appear to have any main code just a collection of subroutines which I assume you copied of the internet. Putting random bits of code together and hoping it will work is not going to get you anywhere. Read the sticky and some of the tutorials. I like the free online book at **broken link removed**. You should read this and try to write your own code.

Mike.
 
thank u for the link Pommie.
But for ur information i only use subroutines for 16 bit multiplication and subtraction. Remaining code is mine.
I am beginer, i started learning about 1 week ago from Nigel Goodwin's tutorials.
You broke my heart.
 
I'm sorry if I hurt your feelings, but if you have written the above code then you have a good understanding of assembler. The small error I pointed out in your code should enable you to get it working.

Mike.

After reading my program,
one thing that i notice for running MPLAB SIM is, there should be some commands after ENDC command.
Then i add
NOP
NOP
Goto Main

Now MPLAB SIM running.
Thanks again
