[gradsusr] Printing out a single value from a grads script

[Charles Seman]

MK,

After "d steering", try adding:

say result
say sublin(result,2)

You can use a combination of "sublin()" and "subwrd()" (and even 
"substr()") commands to extract the desired information from "result"...

For example,

"d steering"
say result
line1 = sublin(result,1) ; word11 = subwrd(line1,1) ; word12 = 
subwrd(line1,2)
say line1 word11 word12
line2 = sublin(result,2) ; word21 = subwrd(line2,1) ; word22 = 
subwrd(line2,2)
say line2 word21 word22

Note, the number of "sublin" and "subwrd" values will depend on the 
"result" so this is why we issue the "say result" command (no quotes in 
script), to see what we've got...  I tried a test in a script I'm 
working on right now, and defined a "line3"  and tried printing it and 
also subwrd(line1,10) (both of which that didn't exist), and the script 
printed nothing but otherwise seemed OK...

For more information on this, please see

Hope this helps,
Chuck
