FUNC rawbytes?

SteveMob

Hello,

I am trying to build a function:
FUNC rawbytes PackCustomMessage(VAR num messageNumber,\VAR string messageString)
        ! Creates a custom message (error/warning/validation)
        ! Inputs:
        !   -messageNumber: num
        !   -optional messageString: string
        ! Returns:
        !   -message2: rawbytes
        .......
        RETURN message2;
    ENDFUNC

I am getting an error saying rawbytes not a value type. So my question is, are there some data types (rawbytes in particular) that the "FUNC" cannot use?

Thanks for any help,
SM

The return statement of a function can only return value types, with as exception dimensioned types (for example arrays). 'Rawbytes' are used as a general data container and can be filled with any type of data (num, byte, string, etc) by means of support instruction/functions; and is thus not a value type.
A workaround is to use a INOUT parameter and thus change the parameter instead of returning a value.
