Typeset -i in MVS (Mainframe system)

Hi,

I have one job that runs daily and creates daily files. At the end I compare the today's file with previous day's file. And if today's file size is greater or equal to previous day's file, then it is ok, else I need to through error.
I have following piece of code:

Code:

typeset -i SIZE_CURRDATE
typeset -i SIZE_PREVDATE
DAY=`echo $RUN_DATE | cut -c 5-6`
if [ $DAY -ne "01" ] ; then
SIZE_CURRDATE=`m_ls -l mfile:file_name |  awk '{ print $5 }' | sed 's/,//g'`
SIZE_PREVDATE=`m_ls -l mfile:file_name |  awk '{ print $5 }' | sed 's/,//g'`

echo "PREV_DATE : " $PREV_DATE
echo "SIZE_CURRDATE : " $SIZE_CURRDATE
echo "SIZE_PREVDATE : " $SIZE_PREVDATE
if [ $SIZE_CURRDATE -le $SIZE_PREVDATE ] ; then
 echo "ERROR : The output file is of zero length."
 exit -1
else
 echo "OK"
fi
fi

This runs fine in AIX UNIX. But it is giving arithmatic overflow error in MVS USS system when file size is more or equal to 10 digits.
Could you please help me to solve this?

sa1

sa1(8)							    BSD System Manager's Manual 						    sa1(8)

NAME

     sa1 -- Generate a system activity daily data file.

SYNOPSIS

     /usr/lib/sa/sa1 [t n]

DESCRIPTION

     The sa1 command is a shell script used to invoke the system activity data collector, sadc.  The binary sample data is collected at intervals
     t seconds apart, in a loop n times.  The binary sample data is written to the standard daily data file, /var/log/sa/sadd where the dd repre-
     sents the current day of the month.

     sa1 is intended to be started by cron.

EXAMPLE CRON ENTRY

     # Starting at 8am collect system activity records
     # every 20 minutes for 12 hours
     # 20 minutes = 1200 seconds
     # 12 hours with 3 samples each hour = 36 loops

     0 8 * * 1-5 /usr/lib/sa/sa1 1200 36

     # After the 12 hour period,
     # collect a system activity report

     30 20 * * 1-5 /usr/lib/sa/sa2 -A

FILES

     /var/log/sa/sadd  Default daily activity file that holds the binary sampling data.  dd are digits that represent the day of the month.
