[ferret_users] Problem with southern polar stereographic plot

[Martin Dix <Martin.Dix@xxxxxxxx>]

I get an error when trying to do a southern polar stereographic plot.
The following example is essentially from mp_demo.jnl

use coads_climatology
! NH version works
! set region/x=0:360/y=0:90/l=1
! go mp_stereographic_north
! SH version fails
set region/x=0:360/y=-90:0/l=1
go mp_stereographic_south
go mp_aspect
go mp_grid sst
fill/nolab/nokey/noaxes sst, x_page, y_page

The NH version works as expected. The SH version gives

**ERROR: illegal limits: "X_PAGE[I=@MAX,J=@MA..." is not in the range
Y=-90:0
         Axis extremes are Y=0.5:10000000
DEFINE VARIABLE/quiet x_axis_range = `x_page[i=@max,j=@max]` -
`x_page[i=@min,j=@min]`
Command file, command group, or REPEAT execution aborted

I'm using
       FERRET v5.81
       Linux(g77) 2.4.21-32 - 07/13/05

I also get the same error with
       FERRET v5.70
       Linux(g77) 2.4.18 - 06/30/04
