It stands for 'bit test file skip if clear' and assuming the Z has been
equated to the Zero flag (bit 2 of the STATUS register), then what the
command is doing is it's testing this bit for a zero value.

If it is set to zero, then the program will skip the instruction following
the btfsc. So for example if you had the following code:

btfsc STATUS,Z
goto X
goto Y

If the 2nd bit of the STATUS register was 0 then the program would execute
'Y' otherwise it would execute 'X'
