This issues a warning: "Test.bas:22: warning: Redundant operation ABS for unsigned value"

Surely if a Byte is signed, then (Byte-Byte) is signed as well?

The compiler is right. At line 22, you have:

Code:

... ABS (yCoords(i) < yCoords(j)) <2 THEN

The ABS argument is a boolean value, which maps to an unsigned byte. Thus unsigned. ;-) I guess you have a bug here, and what you meant was a subtraction, isn't it?
