batch job errors

[Larry Polinsky <ljp@xxxxxxxxxxxxx>]

When submitting a batchjob on our IRIX system (Ferret 5.41)
             ferret -gif < qc_movieF1.jnl>& ferret_output &

The first 2 lines in the script are:
use "/archive/ljp/zetac_STM06/anal/QC_files/qc_history.1022400.nc"
repeat/l=1:5 (let hrs = 740 + (l*4); let bqc=qc[z=1000:10000@ave];
fill/nolabs/nokey/pal=cloud/levels=(-1,4,0.2) bqc[d=1]; go land 7
overlay 1 1; label/nouser -0.8 `($ppl$ylen)/2` 0 90 .16 @ASLatitude;
label/nouser `($ppl$xlen)/2` -0.6 0 0 .16 @ASLongitude; label/nouser
`($ppl$xlen)/2` `($ppl$ylen)+0.75` 0 0 .16 @ASLiquid Water (qc)
STM06; label/nouser `($ppl$xlen)/2` `($ppl$ylen)+0.5` 0 0 .16
@ASVertically integrated from 1000 - 10000 m; label/nouser 0.0 -0.75 -1
0 .18 @ASTime: `hrs` hrs; frame/format=gif; frame/file=qc_Frm`L`.gif)

I get the following:

 **ERROR: command syntax:  /2
          / may not start an expression
PPL %LABEL/nouser -0.8 ` /2` 0 90 .16 @ASLatitude
Command file, command group, or REPEAT execution aborted
 !-> repeat/l=1:5 (let hrs = 740 + (l*4); let bqc=qc[z=1000:10000@ave];
fill/nolabs/nokey/pal=cloud/levels=(-1,4,0.2) bqc[d=1]; go land 7
overlay 1 1; label/nouser -0.8 ` /2` 0 90 .16 @ASLatitude; label/nouser

0 .18 @ASTime: `hrs` hrs; frame/format=gif; frame/file=qc_Frm`L`.gif)

The job then aborts!

However, if I duplicate line 2 such that I have:

use "/archive/ljp/zetac_STM06/anal/QC_files/qc_history.1022400.nc"
repeat/l=1:5 (let hrs = 740 + (l*4); let bqc=qc[z=1000:10000@ave];
fill/nolabs/nokey/pal=cloud/levels=(-1,4,0.2) bqc[d=1]; go land 7
overlay 1 1; label/nouser -0.8 `($ppl$ylen)/2` 0 90 .16 @ASLatitude;
label/nouser `($ppl$xlen)/2` -0.6 0 0 .16 @ASLongitude; label/nouser
`($ppl$xlen)/2` `($ppl$ylen)+0.75` 0 0 .16 @ASLiquid Water (qc)
STM06; label/nouser `($ppl$xlen)/2` `($ppl$ylen)+0.5` 0 0 .16
@ASVertically integrated from 1000 - 10000 m; label/nouser 0.0 -0.75 -1
0 .18 @ASTime: `hrs` hrs; frame/format=gif; frame/file=qc_Frm`L`.gif)

repeat/l=1:5 (let hrs = 740 + (l*4); let bqc=qc[z=1000:10000@ave];
fill/nolabs/nokey/pal=cloud/levels=(-1,4,0.2) bqc[d=1]; go land 7
overlay 1 1; label/nouser -0.8 `($ppl$ylen)/2` 0 90 .16 @ASLatitude;
label/nouser `($ppl$xlen)/2` -0.6 0 0 .16 @ASLongitude; label/nouser
`($ppl$xlen)/2` `($ppl$ylen)+0.75` 0 0 .16 @ASLiquid Water (qc)
STM06; label/nouser `($ppl$xlen)/2` `($ppl$ylen)+0.5` 0 0 .16
@ASVertically integrated from 1000 - 10000 m; label/nouser 0.0 -0.75 -1
0 .18 @ASTime: `hrs` hrs; frame/format=gif; frame/file=qc_Frm`L`.gif)

I still get the error but the job continues and all but the first 6 gif
files are created. I have run this script before under a previous
version of Ferret with no problem. This sort of "get around" is a bit
of a nuisance. Does anyone know why this might be happening?

Thanks.
