Hello, I have got the macro to work quite nicely, but not the way I want it to. I want to learn how to pass a parameter to the macro and from what I can figure out all you have to do is type the variable name after the macro name when you call it right? Here is what I have so far to just print a string to the console
now this works when Is use this
but then fails when I try to pass the parameter from the .data section above the main.
The error it gives is this
1>AM9.asm(30): error A2071: initializer magnitude too large for specified size
does that mean I cant pass the string variable name to it?
Thanks for any help

Shouldn't the string be zero-terminated?
mWriteString MACRO text
LOCAL string
.data
string db text,0
.code
push edx
mov edx,OFFSET string
call WriteString
pop edx
ENDM
Yes I done that too and it still gives me an error I was wondering if that was it but the error seams to be in the main proc and not the marco.
Hold on.. I just re-read your question.
You say : It works as a Macro with a string attached like mWriteString "test" but not when you pass a declared string from data to your macro?

Yes It would work when I set it up like this
Kinda weird I don't know why that even working. It will print out Some String
I am think I am passing something wrong here or do I have the macro mixed up with a procedure?

Well, you cannot pass a declared string to your macro as your macro is setup to declare it to be a new string.
If the macro works then all is well, not?
To pass a declared string you would just call WriteString with the offset of your string and not use your macro.

Oh I see thanks for clearing up that for me. :)
