Hello,

Is there a way to get a string which is the name of the variable passed in parameter of a function ?

I test the type ANY (__System.AnyType) which provides 3 fields (pointer to the value, value size and type class) but not the name of the value.

For example :

FUNCTION func
VAR_INPUT
   info : ANY;
END_VAR
VAR
   infoSize:DINT;
   infoTYPE:__SYSTEM.TYPE_CLASS;
   infoPointer:POINTER TO BYTE;
   infoName : STRING;
END_VAR
infoSize := info.diSize;
infoTYPE := info.TypeClass;
infoPointer := info.pValue;
infoName := "" //???????????????????????

func(GVL.myVar);

Now, I would like to retrieve, in my function func, the name of the variable "GVL.myVar".
I heard about __VARINFO, however I can't find a easy way to retrieve such an information.

Please help

Regards,
