Re: How to do loop in ferret?

[Adam Montano <a_ocean88@xxxxxxxxx>]

Hi,
I do not know much about using the new string
variables in Ferret, but I know that when doing a
repeat loop, the index that you use to repeat on can
make a big difference.  I have done this kind of thing
before and I used it to make this example.  

Say these commands are in the script run_it.jnl

   use coads_climatology
   plot($1) sst[x=180]

Then I would use the K index to run this, since the
coads_climatology data has no depth axis.  Maybe your
I index in the repeat/i=   is causing confusion with
an I or an x axis inside your script.

You can use these commands to run the script for
different regions.

let name = zsequence({"/l=4/x=150:180/y=20:80",
"/l=6/x=100:360/y=-60:60"})
repeat/k=1:2 (go t5 `name`; pause)
