COOL!!! It works like magic!!!!!
Now I have a better idea of the Engine sharing global information.
Just FYI, here are the steps I did:
1. IB thread: save the input file name to a global variable in the “Directory Parse” TPS
2. IB thread: assign the global that contains the file name to USERDATA in IB DATA TPS
3. OB thread: read the USERDATA and set the input file name to the OBFILE, in the OB DATA TPS
You have my sincere thanks!! 😀
