Problem using Objective Analysis



I'm trying to use the objective analysis routines in ferret vs. 5.  Here is
my script:

========== 8< plot.jnl ============================
!
set window/aspect=`213/185`
define axis/y=12.814:13.195:0.001799 YAX
define axis/x=121.447:121.786:0.001847 XAX
define grid/x=xax/y=yax g
file/grid=g/var=lon,lat,h "./ferret.dat"
set var/bad=0 h
let h_grd=scatter2gridgauss_xy(lon,lat,h,xax,yax,2.)
shade/lev=(0)(10)(25)(50)(100,600,50) h_grd,lon,lat
contour/ov/lev=(0)(10)(25)(50)(100,600,50) h,lon,lat
frame/file=plot.gif
========== 8< plot.jnl ============================

When I try "GO PLOT" I get the following:

yes? go plot
!
set window/aspect=`213/185`
 !-> set window/aspect=1.1514
define axis/y=12.814:13.195:0.001799 YAX
define axis/x=121.447:121.786:0.001847 XAX
define grid/x=xax/y=yax g
file/grid=g/var=lon,lat,h "./ferret.dat"
set var/bad=0 h
let h_grd=scatter2gridgauss_xy(lon,lat,h,xax,yax,2.)
shade/lev=(0)(10)(25)(50)(100,600,50) h_grd,lon,lat
 **ERROR: variable unknown or not in data set: YAX
shade/lev=(0)(10)(25)(50)(100,600,50) h_grd,lon,lat
Command file, command group, or REPEAT execution aborted
yes?

Why doesn't this work????

PS

Is there PDF formatted vs. 5 manual available?
