[Implemented] Allowing Logical Statments in Compiler If

It would be great to allow the CompilerIf Statement to accept all of the logical statments; AND, OR, XOR, NOT

CompilerIf can only evaluate expressions with constants, where bit operators &|~! can be used.
AND, OR, XOR, NOT are designed to handle conditions with variables.

He knows that, but he wants to use the other operators with constants as well, which is why he posted in this forum.
You can emulate them using macros:
Code: Select all
Macro COr(A, B)
((((A)<>0)+((B)<>0))<>0)
EndMacro
Macro CAnd(A, B)
((((A)<>0)+((B)<>0))=2)
EndMacro
Macro CXor(A, B)
((((A)<>0)+((B)<>0))=1)
EndMacro
Macro CNot(A)
((A)<>0)
EndMacro
; #MAX_PATH = 1024 Or #MAX_PATH = 260
CompilerIf COr(#MAX_PATH = 1024, #MAX_PATH = 260)
Debug 1
CompilerElse
Debug 0
CompilerEndIf
; #MAX_PATH = 1024 And #MAX_PATH = 260
CompilerIf CAnd(#MAX_PATH = 1024, #MAX_PATH = 260)
Debug 1
CompilerElse
Debug 0
CompilerEndIf
; #ACK = 6 Or (#BEL = 6 And #SYN = 7)
CompilerIf COr(#ACK = 6, CAnd(#BEL = 6, #SYN = 7))
CompilerEndIf
