PA_GetVariableKind returns wrong result?

[Matthias Schmidt-6]

Hello all,

I wanted to implement optional parameters for one command.
So I tried this way:
PA_Variable opt;
       
        opt = PA_GetVariableParameter ( params, 9 );
        int vTyp = PA_GetVariableKind (opt);

although nothing is passed as 9th parameter, vTyp returns 33 =
eVK_Unistring here.
when I open the opt structre fType is 0 '\0'.

Do I miss something here? Is there a better approach with optional parameters?

cheers,
Matthias
