Convert a 'signed' Word to a Long with minimum manipulation ?

[Kamikaze47]

PBP's shift algorithms dont work on negative numbers. You either have to divide instead, or do something like this:

lCTemp=(B5+8)>>4
IF lCTemp.27 THEN lCTemp=lCTemp&$F0000000

(Untested)

*edit* note that the division will always round down (towards negative infinity) when shifting no matter if the number if positive or negative. e.g. 5/2 = 2, but -5/2 = -3 (only for shifting - not division)

Thanks.
It sounds like I should just avoid using the Shift type divides then with Longs...

Just to correct myself, the code in my last post should have been:

lCTemp=(B5+8)>>4
IF lCTemp.27 THEN lCTemp=lCTemp|$F0000000

I accidentally used an AND instead of an OR
