gset does not work + cannot save plots in Octave 2.9.9

[Ayesha Kalra]

Hi

I am using Octave 2.9.9 and was trying to save my plot is .ps format but the command gset is not working. I cannot set terminal to postscript. 

'gset term postscript' gives 

parse error:

  syntax error

>>> gset term

I read somewhere that gset is now obsolete. Is there any other way to save plots in a file  (preferably ps or pdf formats)?

Thanks
Ayesha
