Re: [ferret_users] Shell script arg not working as Ferret variable

[Eowyn.Connolly-Brown@xxxxxxxx]

Thanks, Russ! The \ didn't quite work because Ferret was reading everything after the variable substitution very literally. The eventual solution was: 
let p=${var1:h}[x=0:360,y=-90:90]

In cshell, the :h option gets rid of the default space at the end of every variable inserted. 

Thanks very much!!
