Re: [ferret_users] return y-axis limits

Hi Ferret-users,

I am trying to get the axis max/min values using 'return' command.
Here is an example (I am using Ferret V5.8):

set data NAGa0.01_3d_016_MNA.FILE

let blon = `u[d=1],return=xstart`
 !-> DEFINE VARIABLE blon = 47.52002E
let elon = `u[d=1],return=xend`
 !-> DEFINE VARIABLE elon = 59.68005E
let blat = `u[d=1],return=yend`
 !-> DEFINE VARIABLE blat = 30.73087N <===== NOTE HERE
 **ERROR: command syntax: 30.73087N
          .73087N
DEFINE VARIABLE blat = 30.73087N
Command file, command group, or REPEAT execution aborted
yes?

However, when I issued the command,

yes? say `u[d=1],return=yend`
 !-> MESSAGE/CONTINUE 30.73087N
30.73087N

I do not get any error.

second example:

This is also case with the coads_climatology

yes? use coads_climatology
yes? let blat = `sst,return=yend`
 !-> DEFINE VARIABLE blat = 89N
 **ERROR: command syntax: 89N
          89N
yes? say `sst,return=yend`
 !-> MESSAGE/CONTINUE 89N
89N

Thanks,

Prasad
