Long Variables can be negative?

[Ioannis]

It WILL work only if you use PBPL because the result is stored temporarily in a long variable. This variable is checked, so yes it will work fine.

For more info check the new PBP manual that clarifies the case.

Isn't result stored in BVal in this example?
BVal = BVal - 1
Result in BVal is 255(Checked with debugger). And because BYTE is unsigned it can't be negative. Program won't jump to negative.
Then tried: If BVal - 1< 0 THEN Negative
Then is negative.
I really can't see how value in this statement is stored at end in temp var BVal = BVal - 1.
That code is same as:
Temp=BVal - 1
BVal =Temp
So we loose sing when value is passed to BVal.
I'm done my homework, now you do yours

Page 81 and 82 of my manual... But who reads stinken manuals....

[pedja089]

From manual...
Bval=-1 (Same as Bval =0:Bval=Bval-1)
If ( Bval < 0 ) THEN negative 'Will never test true
So second example from post #4 vil never test true...

What PBP compiler are refering to?

I said, it will work on PBPL

NOT on PBPW

David, the manual I as refering to is the revision of Revised November 28, 2011.
