| 
| If ever I issue the command

| 
| '/usr/tmp/oct-KQRzpx'  "line 1" set nologscale;
|          ^
|          line 0: invalid command
| 
|

| 
| But gnuplot_command_plot is still set to "pl"
| after "clear all":
| 
| octave:2> gnuplot_command_plot
| gnuplot_command_plot = pl
| 
| 
| The error above was produced by the following
| simple script:
| -----------------
| clear all
| 
| x=[0:.1:1];
| y=x.^2;
| 
| plot(x,y)
| 
| x=[0:.1:1];
| y=x.^3;
| 
| plot(x,y)
| -----------------
| 
| the first plot does not appear at all,
| the second produces the error.
| 
| Thanks in advance for any help,

I think this problem is fixed in CVS.

Yes, we are overdue for a new 2.9.x snapshot.
