Whoops!
No need to accommodate contact bounce for the buttons then.
Code:flipflop var bit ‘ 1 = LED is on 0 = LED is off flipflop = 0 ‘ start with LED off at power up, or on if you want to trisb.0 = 1’ buttonA pin input ON trisb.1 = 1’ buttonB pin input OFF trisb.7 = 0’ LED pin output cycle: 'program cycle if portb.0 = 1 then flipflop = 1 ‘ set memory bit endif if portb.1 = 1 then flipflop = 0 ‘ reset memory bit endif portb.7 = flipflop ‘ set LED on or off goto cycle ‘ repeat loop forever
Now, Thats nice and easy. The only thing I would change is not having a variable for the state of the output pin but reading the output state.

In the long run, for midrange pics that don’t have a port latch register,
we should be using a byte port latch to avoid RWM error if time allows.
So it would go, write single bit to port latch byte, write entire port latch byte to port, read back bit from port latch byte.
Not that I can say I’ve ever encountered a problem I’d put down to RWM error.
