You have set the value of your variable "C" in your GDL script.
But you have not set the value of the parameter (if that makes sense).
In you GDL parameter script (or it could be the master script) you should have ...
C = "A" + "B"
PARAMETERS C = C
C needs to be a text parameter of course.
The result for C will be "AB".
