How to determine what are my environment variable are?

To determine your environment variables under Unix, perform:

       RUN          set > /tmp/env.txt

To determine your environment variables under APPX for Windows:

       RUN          cmd /c set >C:\tmp.txt
       RUN          wordpad.exe C:\tmp.txt

 (Under Windows 9x, use command.com rather than cmd.exe.)

If you're running APPX/Client, have the first RUN redirect standard out to a
file in a client-accessible directory, then run an editor on that file.

To get the environment variable using ILF, try;

      SET      --- TEMP 80          =      cd /tmp;
      APPEND   --- TEMP 80          1      set > env.tmp;
      APPEND   --- TEMP 80          1      grep APPX env.tmp >
      APPEND   --- TEMP 80          1                env.txt   ;
      APPEND   --- TEMP 80          1      rm env.tmp
      RUN      --- TEMP 80
