FUNC rawbytes?

in RobotStudio
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.5
