porting pic16f819 code to pic16f877a

how to make pic16f819 asm code run in pic16f877a ?

For starters post where you found this code it was not wrote in asm to begin with and what you posted is the asm code you get after compiling code.

All I no is it runs I have no way to test but simulator and seeing you don't no where it came from and can't tell me what's it to do. I fixed it for the 16F877A

I can't post it its to long It's zipped up
