switch mode inside a ferret session?

[David Wang <climater@xxxxxxxxx>]

Hey Ferreters,

I want to generate both metafile output and gif output in one .jnl 
script. But my X.org is configured in 16-bit color depth and cannot be 
changed at this moment for some reasons. So within the session of normal 
mode, ferret is unable to create gif images by using 
FRAME/FILE=filename.gif. Here I am asking if it's possible to switch 
ferret to -gif batch mode from the normal mode w/o starting a new session.
Or if ferret can tell me which mode it's running, IF-THEN-ELSE may be 
used to bifurcate the right output commands for either mode in one script.

Thanks, D.W.
