Wouter,

As mentioned before, everyone seems to get the single instruction i the body
of the if right.

What is a lot trickier is 'hoisting' code out of the if so that the body
_becomes_ one instruction.

For example:

    fred = 10
    if (RB0)
        fred = 20

can be (best):

    movlw    10
    btfsc       RB0
    movlw    20
    movwf    fred

or even (better):

    movlw    10
    movwf    fred
    movlw    20
    btsc        RB0
    movwf    fred

but tends to be (acceptable):

    movlw    10
    movwf    fred
    btfss       RB0
    goto       over
    movlw    20
    movwf    fred
