This could be tricky since the program uses the environment variable A/g/i/l/e/e/s/o/f_license_file to point to the license file.
I suppose you could change the license file names back and forth.
Another thing to try is to write a scipt to do this. This is covered on page 3-15 of the install manual.
Another thing to try is to combine the files into the same file. This is on page 4-20.
You could also start l/m/t/o/o/l/s, change the pointer to the appropriate license file and the start the server and re-read the license file.
As a note, here at work we have only one license file on the network and it works on both 2002 and 2002C. So why do you need two different ones?
