Directly pass parameters to pbs script - bash

Question

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.

The qsub utility can read the script from the standard input, so by using a here document you can create scripts on the fly, dynamically:
#!/bin/sh
for i in `seq 1 10`
do
cat <<EOS | qsub -
#!/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 $i
EOS
done
Personally, I would use a more compact version:
#!/bin/sh
for i in `seq 1 10`
do
cat <<EOS | qsub -V -S /bin/sh -N pass_test -l nodes=1:ppn=1,walltime=00:02:00 -M XXXXXX#XXX.edu -
cd /scratch/XXXXXX/pass_test
./run_test $i
EOS
done

You can use the -F option, as described here:
-F
Specifies the arguments that will be passed to the job script when the script is launched. The accepted syntax is:
qsub -F "myarg1 myarg2 myarg3=myarg3value" myscript2.sh
Note: Quotation marks are required. qsub will fail with an error
message if the argument following -F is not a quoted value. The
pbs_mom server will pass the quoted value as arguments to the job
script when it launches the script.

If you just need to pass numbers and run a list of jobs with the same command except the input file number, it's better to use a job array instead of a for loop as job array would have less burden on the job scheduler.
To run, you specify the file number with PBS_ARRAYID like this in the pbs file:
./run_test ${PBS_ARRAYID}
And to invoke it, on command line, type:
qsub -t 1-10 pass_test.pbs
where you can specify what array id to use after -t option
