How to define two digits variable in shell script?

Dear Shell script Experts,
I am working on shell script which is defined here, qsub_seq.csh [1]. The purpose of this script is to read few input files (with defined starting index and last index) and make processing faster over server.
For some task, I had 1064 of input files, so I wrote another script, [2] to make it quicker.
However, instantly I realized that it failed to work as the qsub_seq.csh script read the first digit of the input file and delete them all, though my input files have range from 0 till 1064, as given some examples of input files [3].

Any help, how to make qsub_seq.csh read two digits variable?

thank you in advance,

[1] qsub_seq.csh
# $1 - code name

# $5 - starting index

From top to down:
1) This part is not required:
if [ $Start -ge $Entries ]

As long it is lesser (-lt) it cannot exceed equal or greater than STOP, and will therefor break anyway.
2) Why not make STEP = 8, rather than END = START + STEP (9) - 1
3) I'm not familiar (enough) with cshell, but what happens in: ./ $1 $2 $4_$2_$n
4) (one could write functions instead of different files)
5) You do overwrite the START variable before the loop ends, is that intended?

Last but not least, try to execute your scripts verbose / in debug mode, to see where the issues are, and how they look like:
 sh -x

And within ./qsub_seq.csh, change the shebang to #!/bin/csh -x (if that option is available for csh?)

Actually, I can't see how and where

. Possibly when passing parameters?
Wouldn't it make sense to collect the entire task into one single (sh-, bash-, ksh-) script?

I see a problematic
  ls $3/$4/$4_${n}*.root > $4_$2_$nby

Perhaps you can simply omit the *?

Hello all,
Thanks for your replies, it helped me to dig it further.
Now, I realize I shall be able to fix it, if I could figure out how to provide the command line in a shell script to create directory/anotherDirectory. Any hints are appreciated..
Basically, I want to do somethiing like this :


./qsub_seq.csh  file.conf /inifitla/input/file/location Directory/subDir$Start 0 2

Basically, I want to redirect the output to '

' which I have to create.
