Hello David,

So it means that 'axis' becomes a 100% worthy plot command when you
use /Save (So /Save means "Yes, save the !y.crange")? And then use
yrange for the range. And it was the range that made me use another
'plot' command in my real implementation. Thanks, now I can tidy up my
code (if still possible).

Regards,
Joost
