Hi,

I have defined the following:

FUNCTION_NAME EQU FunctionPoly

I want to create something like the following but using "FUNCTION_NAME":

public FunctionPoly_Handler

So, I have tried different approaches like:

Code:

public FUNCTION_NAME_Handler
public FUNCTION_NAME#_Handler
public #FUNCTION_NAME#_Handler
etc.

But all of them are incorrect. Is that possible?

Thanks![/b]

You need to use MATCH to extract the value of FUNCTION_NAME into a parameter, then the value of parameter can be concatenated with #:

Code:

match name, FUNCTION_NAME {
    public name#_Handler
}

Hi Tomasz,

Thanks again! That works as expected!

The problem is that I'm using it inside a macro and I don't get it to work. I have tried the following:

Code:


FUNCTION_NAME EQU FunctionPoly1

macro POLY_FUNCTION
{
   match name, FUNCTION_NAME \{
   public name#_handler
   proc name#_handler param1
   \}

        mov     eax, eax 
        ret

    endp
}

; Testing the waters....

POLY_FUNCTION

mov     eax, FunctionPoly1_handler ; FASM ERROR: undefined symbol 'FunctionPoly1_handler'.

mov     eax, name_handler ; it assembles correctly!!!

When the "match" is inside the macro, it does not get defined as expected. If I put the "match" ouside the "macro" it works fine. How can I make it work from inside the macro?

Thanks!

You need to escape the "#" operator the same way as you escape the "{" and "}", otherwise it is processed by the outer macro.

Hi,

I have done some changes. When I put in the above example:

Code:

...
public name#_handler 
...

It's processed correctly and generates "public Function1Poly_handler"

But if I put the following:

Code:

...
public name#_handler as '_name#_handler@8'

or 

public name#_handler as '_#name#_handler@8'

it seems to be processed as:

public Function1Poly_handler as '_name#_handler@8'

That is, the second part is not processed.

Any help?

Thanks!
