Help with error 484

[Brian Alvarez]

I am working with a class, and i need to make conversions for all datatypes (a class for associative arrays), but, writing code for each class method would be too tedious. So, i was thinking i could generate methods with macros... and i ran across this error:

Error 484 - Requires procedure (Function/Method...)

Requires procedure (Sub/Function/Method/Property) - The statement or function found here is only allowed within a procedure (SUB, FUNCTION, METHOD or PROPERTY). Elsewhere, it has no valid meaning and must be removed.

Basically what i am trying to do is generate apointer method, a getter and a setter, this is the macro code:

MACRO ASC_PLB_VAR_HANDLER(DT,GS,PT,TP)
    METHOD PT(BYVAL k AS STRING) AS DWORD
    END METHOD
    PROPERTY GET GS(byval k as string) AS DT
    END PROPERTY
    PROPERTY SET GS(byval k as string, BYVAL v AS DT)
    END PROPERTY    
END MACRO

And i am invoking it like this:

ASC_PLB_VAR_HANDLER(INTEGER,sInt,pInt,1)

The macro is being invoked from within the INTERFACE body of a class... like this:

CLASS PluriBASIC_Associative_Class
    INTERFACE PluriBASIC_Associative_Interface
        INHERIT IUNKNOWN
        ASC_PLB_VAR_HANDLER(INTEGER,sInt,pInt,1)
    END INTERFACE
END CLASS

Am i doing something wrong or is it an error from PowerBASIC?

Strange workaround i found... modifying the macro like this::

MACRO ASC_PLB_VAR_HANDLER(DT,GS,TP)
    END METHOD
    PROPERTY GET GS(byval k as string) AS DT
    END PROPERTY
    PROPERTY SET GS(byval k as string, BYVAL v AS DT)
END MACRO

And invoking it like this (for each datatype):

METHOD pInt(BYVAL k AS STRING) AS DWORD
   ASC_PLB_VAR_HANDLER(INTEGER,sInt,1)
END PROPERTY

Strange! is that a work-around or just a compile-around? Could you use PB Collections or even iDictionary interfaces?

[Brian Alvarez]

I think it is a compile-around as you say. For the rest, yes, no problem, it all works fine once compiled. I think it is just that classes are block scanned and nothing else is expected besides methods. Once it finds one, macros work with no issues.
