There's always a program running (the GEM DESKTOP is just an ordinary TOS
program, loaded from ROM instead of from disk). If you mean, "is the
currently running program not the desktop", you might try the shel_read
AES call:
   char pgmname[128], cmdline[128];
   if (shel_read(pgmname, cmdline) == 0)
       printf("an error occured\n");
   else
       printf("the desktop thinks %s is the currently running program\n",
          pgmname);

Note also that the desktop's idea of what the current program is may not
correspond to reality, since if a program run from the desktop runs
another program, there's no way for the desktop to know.
