[ferret_users] [ferret users] having variable in return=dsetnum command

[Mark.Collier@xxxxxxxx]

use levitus_climatology

let id="`temp,return=dsetnum`"

 

gives the data set number.

 

Is it possible to put a variable in the _expression_, something like (but this doesn’t work)?

 

let ivar=”temp”

let id="`ivar,return=dsetnum`"

 

Thanks,

Mark.
