External editor

[Krzysztof Gozdziewski]

Hello !

I have a problem with calling an external editor from within a session
of octave. If I try to define a command like

    ed = system( "joe", "myfun.m" )

the editor 'joe' hangs the session at the start and I have to kill 
the process of octave. The same is with vi.

We use octave on SunOS4.1.3 and 5.3, the shell is tcsh.

Sorry if I overlooked a strightforward solution to this problem.
If someone knows it please replay. I need the editor for
writing function and program files when having only one text terminal.

Thanks in advance. 
With best regards
