Jeff,

Thank you for that comment. It is working now, but not doing exactly what I
want. I am still having the problem with the parea:

SET error:  Missing or invalid arguments for PAREA option
SET error:  Missing or invalid arguments for PAREA option

=======
Help me check if the quotes are properly placed,
'set parea 'xlo 'xhi' 'ylo' 'yhi'

Note: I had earlier defined xlo, xhi, ylo, and yhi.
I want to be able to plot a figure with say 12 panels, but what I am
getting presently is 12
different plots.

Thanks,
Abayomi
