Dear Ferreter,

Using Ferret 5.81, it is easy to make a plot using an open-ended levels.

How do use this mode when using Ferret v5.70 on Mac.

I tried the following command, but it doesn't work.

use coads_climatology

shade/lev=(-inf)(5,30,5)(inf)/l=1 sst

**ERROR Syntax error

LEV,()(-INF)(5,30,5)(INF)

I would be grateful for clues/ as to how to solve it.

Thank you.
