For all of the API functions I tested, the program returned:
LENGTH: 00000001
SIZE: 0000FF04
TYPE: 0000FF04
OPATTR: 000003A5
References a code label
Is an immediate expression
References no undefined symbols and is without error
References an external label
STDCALL
Press enter to exit...

BTW, MichaelW, can you to explain what means the value "0000FF04", returned by TYPE? According to masm32.hlp, when the expression is code label, it should be distance, but I doubt about it, since the SIZE returns the same value.
I've found nothing about labels and TYPE in MASM programmer's guide.

I have no idea what the 0000FF04 value is. [...]
I've just found it in MASM Programmer's Guide 6.1: :)

Without OPTION M510, SIZE returns values of 0FF01h, 0FF02h, 0FF04h, 0FF05h, and 0FF06h for SHORT, NEAR16, NEAR32, FAR16, and FAR32 labels, respectively. LENGTH returns 1 except when used with DUP, in which case it returns the outermost count.
Not much of use, thought...
I think it might have been useful for DOS code, say for a macro where you needed to know the distance for a label. I can't see any use for Win32, but all knowledge is good knowledge, so thanks for taking the time to post this. :U
