".if eax > 0" error (warning A4010:expected '>' on text literal)

[caraveiro]

Hi.
I just cannot compile when the condition is ".if eax > 0".   

I have review the vasily.inc file and temphls.inc and I guess there is some macro logic messing around.
So far I'd run out of clues.

¿Any idea what's going bad in my code?

I don't have temphls.inc on my computer but...
try this

Code Select Expand


include \masm64\include64\masm64rt.inc

.code

WinMain proc
    invoke MessageBox ,NULL, addr MsgBoxText, addr MsgCaption, MB_OK

    .if rax == 0                                ; or did you really want eax here? 

        .if rax } 0                               ; in masm64  use'}' in place of '>'

;; put you statement here

        .endif

    .endif
    invoke ExitProcess,NULL
WinMain endp

MsgCaption      db "Iczelion's tutorial #2",0
MsgBoxText      db "Win64 Assembly is Great!",0
END

Also you are using code after invoking ExitProcess.
After ExitProcess finishes the program will immediately close.
That code will never run unless a jump directs the flow of code to there.
I changed eax to rax, since I assume that is what you meant
I moved the .if block to above the call to ExitProcess, should assemble fine.

see attachment '1.zip' below.

Need further help? All you need is to ask.

ML64 does not allow that notation.

.if eax > 0

Use this instead,

.if rax } 0

Have a look at the "MASM64 Library And Macro Reference" help file under the heading,

Control Flow Operators
.if Block Comparison Operators

That's the reference I needed, hutch.

            ;.if ((cl!=0)&&(cl!='') ;note this masm32 code, like girlfriend, NEEDs SPACES in masm64   :bgrin:
            .if ( (cl {} 0) && (cl {} ' ' ) )
            .endif

Thank, swordfish.

You're welcome. Glad your all sorted.
