gset error

Hi I'm trying to save a plot, following the method of Chapter 1 in the manual. which says " gset term to see a list of the supported terminal types. Octave uses gnuplot to display graphics, and can display graphics on any terminal that is supported by gnuplot. To capture the output of the plot command in a le rather than sending the output directly to your terminal, you can use a set of commands like this gset term postscript gset output "foo.ps" replot " However, every gset command gives an error. gset term parse error: syntax error gset term ^ How to proceed? This is Octave 2.9.9 under Fc6. -- Mark van Rossum, Lecturer, ANC Rm D7, 5 Forrest Hill, U. of Edinburgh, Edinburgh EH1 2QL phone: +44-131-6511211 +44-131-5538885 (home)+44-7722049644(m) http://homepages.inf.ed.ac.uk/mvanross
