Multiple commands per line at grads shell prompt

[P.R.]

Quick question:
Is it possible to type in multiple commands on a single line at the grads
command prompt?
I don't think it is, but I just wanted to confirm this...
Something like this:

ga-> clear ; set gxout shaded ; set clevs 5 10 15 20 30 40 50 ; d tmp

(This example obviously doesn't work.)

If this isnt possible, then I'd also like to mention it as a feature request
for COLA.
It would help slightly speed up entering&processing commands & maybe make
working with at the grads prompt a little bit easier...

Thanks,
P.Romero
