After a successful FB-5 call the writing can be done via the returned address of the FB 5 parameter ("VarToken")
with the help of FB3.

Call example 2
Read a GUD variable from channel 1 with the name "GUD_STRING" (type definition of the variables: STRING
with length 30 bytes). The user-defined variable should be converted in a 10-byte variable pointer for subsequent
writing with the FB 3.
Call and parameterization of FB 5 with instance DB 111:
// Data block for GUD variable
