[gradsusr] multiplication in Grads script

[Stephen McMillan]

Kathryn,

I don't see anything wrong with what you are showing, as the following (in
a script) produces 1.12 0.047 0.05264 on screen...

xdif=1.12
xplot=0.047
xdist=xplot*xdif
say xdif' 'xplot' 'xdist

Perhaps you're getting the error because you have no gridded file open
prior to running?
