What is happening here, is that the code is trying to access a variable field within the callstack and not within the local program memory, this is a little trick that we do when working within user exits and we don't have a specific field or internal table being passed to the exit's funciton module. Here the program name is specified and then immediately, the variable name, or this could be an internal table name as well. By assign to a field symbol, you can then gain access to this variable from your program, which of course could be very dangerous, so be careful.
