Put fitting results/parameters on the plot/graph?

[Sun, Mingzhai]

Hi, 
 The problem I have is the following:

 for i=1:10
  output_filename=["result", i, ".ps"]
  gset output output_filename #Here is one problem!!!!!!!!
  gset terminal postscript
  gset label "i=%g", i at graph 0, 0.2 #Another problem!!!!!!!
  grid on
  plot(x, y)
 end

As I indicated above, there are two problems. 
1. I can not change the output file name as the loop goes on. Actually 
what I really got is: "output_filename". What I really want is to have
file names 1.ps, 2.ps etc. 
2. I want to put the i's value on the graph, so that I can which i value 
the graph is corresponding to. But octave told me that "i" is not undefined
variable.

I searched using google, but I could not get the solution for these two
problems. 

Any suggestions?
Thanks in advance.

Ming
