assign figure numbers incrementally

[Kamaraju S Kusumanchi]

I have a octave script which is as follows.

# some lines
figure(1)
plot something here
# more lines
figure(2)
plot something here

The disadvantage with this approach is that, If I rerun the script (after
making some changes), the previous graphs are overwritten. Is there any way
to do something like

# some lines
figure(current figure number + 1)
plot something here
# more lines
figure(current figure number + 1)
plot something here

This way, If I make changes in the script and rerun it, the old figures will
not be overwritten and will be plotted in new windows. Is this possible in
octave? I am using Debian Etch, octave 2.9.9.

I have searched in the octave documentation and in goodle but could not find
anything there.

thanks
raju
