Does Debug consider ~a as ~integer?
Code: Select all
a.a = 1
Debug ~a ; -2
a = ~1
Debug a ; 254

PB result is absolut correct.
.a is an ASII = unsigned Byte 0..255.
Not 1 = 254 -> correct

Be careful. The debugger considers everything as a signet. Is unfortunately so ;(

Yes, but for the program is an unsigned byte. It's a debugger output failure ...

Code: Select all
a.a = 1
Debug Bin(~a,#PB_Ascii) ; -2
a = ~1
Debug Bin(~a,#PB_Ascii) ;

Resuming:
Bitwise operations on variables in Debug always return a (signed) Byte!
Be careful!
