[gradsusr] Extracting variable description and units from control file for use in string/title

[Joe Moore]

Yeah! So I could do something like:

'q ctlinfo'
temp=sublin(result,10)
desc=substr(temp,10,20)
'draw string 4.5 8.3 description is 'desc

That could work, but I didn't know if there was a more simple way of going
about it.
