Re: using user defined variable in ferret script

[Jaison Kurian <jaison@xxxxxxxxxxxxxxxxxx>]

Hi Angelika,
              Few corrections to your script : 

    1. you defined ymin1 & ymax1 but in the plot command with vlimits
            you used different variable names ==> "ymin" & "ymax"
            ==> it should be "ymin1" and "ymax1"

    2. "ymin1" and "ymax1" is defined over var1 but while plotting you
            used var, it should be var1

    3. to extract the values, you have to use grave accents "`" & not the
            single quotes "'" as shown in the example below

 Hope this helps

 With Regards 

 Jaison

---------------example.jnl-------------
\ cancel mode verify

      use coads_climatology
      set reg/j=46/l=1

      let min1=sst[i=@min]
      let max1=sst[i=@max]   
    
      list/nohead min1, max1

      plot/vlimits=`min1`:`max1` sst
