Plotting Question

[Thomas D. Dean]

Linux X11.

I have a script that works when sourced from within octave, but, when I 
start from the command line, I get no plot.

> cat dotest.m
1;
A  = load ( 'test.dat' );
ax =plotyy(A(:,1)/1000, 20*log10(A(:,3)./A(:,2)), A(:,1)/1000, A(:,4));
title  ( 'Insertion Loss and Phase' );
xlabel ( 'Frequency kHz' );
ylabel ( ax(1), 'Insertion Loss db' );
ylabel ( ax(2), 'Phase, debrees' );
ylabel ( ax(2), 'Phase, debrees' );
legend ( 'Insertion Loss','Phase' );
grid on;
ans = input ( 'Press return to close plot and exit' );
close all;

> /usr/local/bin/octave dotest.m
Press return to close plot and exit

No plot displayed.

I believe this has to do with the shell, bash, forking and then exec'ing 
octave.  Correct?
