Oh yeah, I forgot to answer the basic question from this tread.

If you want to accomplish the equiv. of (Var = XXX) you can do this:

bitvarY = (bytevarX = 254)

You can do this:

bitvarY = 1 - (- ABS(bytevarX - 254) >> 15 )

Again, this is ugly but it accomplishes the result you want without an IF statement.

If you are looking to minize code size you may want to try NCD

bitvarY = 1 - (- NCD(bytevarX - 254) >> 15)

Another hack to try would be to use bitwize XOR for your compare test -- thinking about it, this may be the fastest and tightest way to do it;

bitvarY = 1 - ( - (bytevarX ^ 254) >> 15)

Yet another thing to try is the Pbasic's normal truncation and the REV function rather than the "-" sign and the ">> 15" business. The whole purpose of these things is to take advantage of all numbers but zero have a negative with a 1 in the high order bit of a 16 bit number.

You can get t this bit in an expression using the following as well:

bitvarY = ( - (bytevarX ^ 254) REV 16)

The above also reverses the sense of bitvarY. It becomes 1 in they are different and 0 if they are equal.

This brings up another simplification. Changing bitvarY to the opposite sense (bytevarX <> 254) makes the test a bit easier to implement as all the "1 -" s from the above expressions disappear.

Hope this helps.
