PIC asm : how to get indirect bit value ?

[tgq]

hi
how can I make indirect access to check a special bit ?
it will be like BTFSS Mem,BitPosition but BitPosition should be a variable from 0 to 7 representing the bit number to check
Thx

You can do it in various ways, but no one is quite short. For example, you can decrement the variable BitPosition in the loop while in the same time rotate Mem to the right. When BitPosition is 0, go out from the loop and test BTFSS Mem,0.
