wierd problem with go scripts

[Brent A McDaniel <gte328r@xxxxxxxxxxxxxxxxxxxxx>]

Hi Ferreters,

I'm experiencing a wierd bug on my system that I wasn't able to find in
the mail archives.  The basics of it are: if I try to call certain go
scripts (.jnl) from the unix command line (ferret -batch < scriptname.jnl
), it completely fails, but if I enter the exact same commands manually that the
script would have run, it works fine.  If I try to call the same script
from within ferret (yes? go scriptname.jnl), it works fine.  This is a
problem as I'm trying to use shell scripts to automate some data analysis.
I've called .jnl files from the command line using ferret -batch <
scriptname.jnl before and it's worked ok but the scripts were shorter in
length.

Here's the script that I'm calling:
[gte328r@ao qdata2]$ more aanomreg.jnl


set memory/size=100
use aoindex.cdf
use aanom.1958.nc
use aanom.1959.nc
use aanom.1960.nc
let
testa2=airanom[d=2,z=1000,t=1-jan-1958:28-feb-1958]*index[d=1,z=1000,gt=`airanom[d=2],return=GRID`@asn]
let
testb2=airanom[d=2,z=1000,t=1-dec-1958:31-dec-1958]*index[d=1,z=1000,gt=`airanom[d=2],return=GRID`@asn]
let temp2=testa2[t=1-jan-1958:28-feb-1958@sum] +
testb2[t=1-dec-1958:31-dec-1958@sum]
let
testa3=airanom[d=3,z=1000,t=1-jan-1959:28-feb-1959]*index[d=1,z=1000,gt=`airanom[d=3],return=GRID`@asn]
let
testb3=airanom[d=3,z=1000,t=1-dec-1959:31-dec-1959]*index[d=1,z=1000,gt=`airanom[d=3],return=GRID`@asn]
let temp3=testa3[t=1-jan-1959:28-feb-1959@sum] +
testb3[t=1-dec-1959:31-dec-1959@sum]
let
testa4=airanom[d=4,z=1000,t=1-jan-1960:28-feb-1960]*index[d=1,z=1000,gt=`airanom[d=4],return=GRID`@asn]
let
testb4=airanom[d=4,z=1000,t=1-dec-1960:31-dec-1960]*index[d=1,z=1000,gt=`airanom[d=4],return=GRID`@asn]
let temp4=testa4[t=1-jan-1960:28-feb-1960@sum] +
testb4[t=1-dec-1960:31-dec-1960@sum]
let reg1 = temp2 + temp3 + temp4
save/file=aanomtemp.nc reg1
quit




It's hard for me to debug what's going on as the error messages are
garbled to say the least.  Here's what I get when I try to call the script
from the command line:

[gte328r@ao qdata2]$ ferret -batch < aanomreg.jnl
 	NOAA/PMEL TMAP
 	Program FERRET
 	Version 5.22 - 07/27/00
 	09-Apr-01 17:34

yes? emp3 + temp4
 **ERROR: unknown command: emp3
yes? save/file=aanomtemp.nc reg1
 **ERROR: variable unknown or not in data set: REG1
yes? quit

I'm running ferret v5.22 on a linux machine.  Has anyone else experienced
this?  Is it a linux problem only?

Thanks for any help.

Brent
