Loop through variables

I am pretty new to Unix. Trying to pick up some slack while a coworker is out on vacation.

Basically the script is working fine however when I go through the testing phase and have to make mods it is a pita.

Here is an example of what I have

Code:
#!/bin/ksh
if [ ! -s "${DATAPATH}/${src_file_1}.csv" ]
then
    echo "${src_file_1}.csv is missing" >> ${file_log}
    fi

That is a small piece. There are several other areas alot more complex. There are 36 csv files that we are loading into a reporting website every quarter. Each variable ties to a file name. That being said we have variable names from src_file_1 through src_file_36. My thought is that I could generate a loop that would change the variable name with each cycle.

Thanks in advance for any insight.

Got it figured out...

Code:
for i in ${src_file_1} ${src_file_2} ${src_file_3} ${src_file_4} ${src_file_5} ${src_file_6} \
${src_file_7} ${src_file_8} ${src_file_9} ${src_file_10} ${src_file_11} ${src_file_12} \
${src_file_13} ${src_file_14} ${src_file_15} ${src_file_16} ${src_file_17} ${src_file_18} \
${src_file_19} ${src_file_20} ${src_file_21} ${src_file_22} ${src_file_23} ${src_file_24} \
${src_file_25} ${src_file_26} ${src_file_27} ${src_file_28} ${src_file_29} ${src_file_30} \
${src_file_31} ${src_file_32} ${src_file_33} ${src_file_34} ${src_file_35} ${src_file_36} 
 
do 
if [ ! -s "${DATAPATH}/${i}.csv" ]
then
    echo "${i}.csv is missing" >> ${file_log}
    fi
    
done

NAME
smrsh - restricted shell for sendmail SYNOPSIS
smrsh -c command DESCRIPTION
The smrsh program is intended as a replacement for the sh command in the prog mailer in sendmail(1M) configuration files. The smrsh program sharply limits commands that can be run using the |program syntax of sendmail. This improves overall system security. smrsh limits the set of programs that a programmer can execute, even if sendmail runs a program without going through an alias or forward file. Briefly, smrsh limits programs to be in the directory /var/adm/sm.bin, allowing system administrators to choose the set of acceptable com- mands. It also rejects any commands with the characters: ,, <, >, |, ;, &, $, (<RETURN>), or (<NEWLINE>) on the command line to pre- vent end run attacks. Initial pathnames on programs are stripped, so forwarding to /usr/ucb/vacation, /usr/bin/vacation, /home/server/mydir/bin/vacation, and vacation all actually forward to/var/adm/sm.bin/vacation. System administrators should be conservative about populating /var/adm/sm.bin. Reasonable additions are utilities such as vacation(1) and procmail. Never include any shell or shell-like program (for example, perl) in the sm.bin directory. This does not restrict the use of shell or perl scrips in the sm.bin directory (using the #! syntax); it simply disallows the execution of arbitrary programs. OPTIONS
The following options are supported: -c command Where command is a valid command, executes command. FILES
/var/adm/sm.bin directory for restricted programs ATTRIBUTES
