Call program in EVALUATE clause

Hello (again).

I have a program that reads records in a .txt file. Depending on the content of that file
it will determine what program is to be CALLed next. The records are read into a structure in 
WORKING-STORAGE SECTION. The content of the txt file is written manually.

If someone is very interested:

The CALLed program displays "hello"... The main issue is that TBN01002T
be called. I have displayed f1-prg and it displayes TBN01002T, so I don't see how
TBN01002T could be a problem. Any help would be very appreciated!
