Has anyone successfully created a window with a CLI in it?  According to the
manuals, you are supposed to use execute with an empty string, a file handle
referring to a new window, and 0 for the output.

     I tried the following:

nullstring[0] = '\0';
execute(nullstring, &W, 0);

where W is the pointer to the window I just opened.  The results were that the
screen went all black, and the program acted as if it were dead (or not having
access to i/o).  I then changed the execute command to be:
    
execute(nullstring, W, 0);

and this caused the machine to crash.
  
     My question is:  just what is meant by a file handle to a new window?
What am I doing wrong?  Also, the reason I am doing all of this is to allow
users of my program access to multitasking even though my program uses a
customscreen.  My solution is to create a dummy window with a NEWCLI in it.
Is there some better solution to this problem?

                                           Thanks in advance,
