[gradsusr] multiplication in Grads script

[Love, Mr. Gary, Contractor, Code 7542]

These three lines work fine with every version of grads I am using. However, I 
use a simple text editor like view to write a script.



I suspect your text editor is adding hidden characters that grads cannot 
interpret.  This is why a value is not being assigned as indicated by the 
error.



Try a linux editor such as vi, emacs, or nedit to write your script.

Subject: [gradsusr] multiplication in Grads script



I have defined 2 variables in a grads script which I would then like to 
multiply

to obtain a 3rd variable

xdif=1.12

xplot=0.047

xdist=xplot*xdif

I get the following error "Non-numeric args to numeric operation"

I have tried multiple ways to get this to work with no success ... guessing 
that it is commenting out "xdif" but I also tried putting * in quotes and that 
produced a similar error.

Any Ideas?

Thanks!
