Hi Jinx,

contents of byte =3D decimal 8 - is that what you meant to type rather than=
=20
bit 3 of byte?

You confused me there with the word elses, but yes sort of, the first IF is=
=20
tested, and if found to be false it will jump to -

:: tempstep >>=3D 1;shift #1

But if diff was equal to and greater than tempstep, you would have the IF=20
statement and what is between the braces will be executed AS WELL as the=20
tempstep code and so on down the list.
