Getting that first one running is always a big step and very
satisfying. Plus it's something to build on. A couple of minor
things

>  decfsz CounterB,1

could / should be written as "decfsz CounterB,f". The default is "f"
so "decfsz CounterB" will work. A lot of 0's and 1's in code may
prove to be confusing one day. Stick to f and w

>  bsf STATUS,0 ;changes carry bit, etc

"carry" and "zero" can be defined, #define carry  status,0 so
you could use eg btfsc carry, or "skpnc" is an alternative

Have a look in Help/MPASM Assembler Help (path depends
on what version of MPLAB you're running). And check out
16F877.inc (just load it into MPLAB or any WP) to see what
labels / bits and mathematical operators are already defined
or acceptable shortcuts

Happy late nights !
