Am I running Java Client?

Is there a way to determine if APPX Java Client (rather than Windows Client, or character based APPX running) is connected, to determine what type of menu should be displayed (for example)?

In APPX 4.1 and higher, you can use the following code:

      SUBR --- CHECK GUI CLIENT     SUBPROCESS  END? N
      IF   --- RETURN CODE             EQ    1
T     it's the java client
F     it's not
