How do you Detect 32-bit or 64-bit Compiler Versions?

@Dude
It is not a good behavior to extend a thread with a question that has nothing to do with the original topic. It'll only lead to confusion like this.

Well, I think it is consequent: It was he who extended this thread and now it is he who is confused ...

Sorry Mijikai and Little John; I misunderstood what was happening with SizeOf(). I'll take my leave now.

How about testing length of default integers. Code below shows the difference.

Code: Select all

[/Dim a(2)          ;64-bit systems each element is 8 bytes
Dim b.l(2)        ;32-bit systems each element is 4 bytes like this
a(1)=-1
b(1)=-1
Debug PeekB(@a(1)+4)   ;5th byte of 8 bit word
Debug PeekB(@b(1)+4)   ;1st byte of next 4 bit word
End
code]

How about testing length of default integers

For this you can use:

Code: Select all

SizeOf (Integer)

SizeOf() can also be used with CompilerIf.

As said by Mijikai earlier

How about:

Code: Select all

Debug SizeOf(Integer)

Thank you Little John for cross-platform giving.
Maybe CPUID asm op could allow including Mac and pass API.
