Directly pass parameters to pbs script

Is there a way to directly pass parameters to a .pbs script before submitting a job? I need to loop over a list of files indicated by different numbers and apply a script to analyze each file.

The best I've been able to come up with is the following:

#!/bin/sh 

for ((i= 1; i<= 10; i++))
do
        export FILENUM=$i
        qsub pass_test.pbs
done

where pass_test.pbs is the following script:

#!/bin/sh

#PBS -V
#PBS -S /bin/sh
#PBS -N pass_test
#PBS -l nodes=1:ppn=1,walltime=00:02:00
#PBS -M XXXXXX@XXX.edu

cd /scratch/XXXXXX/pass_test

./run_test $FILENUM

But this feels a bit wonky. Particularly, I want to avoid having to create an environment variable to handle this.
