Please decode in English

Hello: Can anyone please decode this script in English. I have also made some comments which I know.. The actual script does not have one comment also..

#! /bin/ksh

. odbmsprd_env.ksh #setting the env..

echo $0 Started at : `date '+%d-%m-%Y %H:%M:%S'`
# what's echo $0

curdt=`date '+%Y%m%d%H%M%S'`

file=rpt
# why file=rpt

#what's $# ==3 -- I know we pass 3 parameters to the script and 3rd param is file name and 1st is startdate and 2nd is enddate.

if (( $# == 3 ))
then
echo arguments: $1 $2 $3
sql @rcvdata_p.sql $1 $2
file=$3
fi

# We are calling sql scripts to do some processing.
sql @rcvstmt3_p.sql
sql @rcvrep_p.sql

# We are checking number of lines in the file pur_jur.csv
lns=`cat pur_jur.csv|wc -l`

# If we have lines in the file, then do processing
if (( $lns > 0 ))
then
echo $lns records found in PURCHASE JOURNAL
# Debug into english the next line
sed 's/ //g' pur_jur.csv|sed 's/,//g'|sed 's/|/,/g' > pur_jur1.csv
# I understand the rest of the program
mv pur_jur1.csv pur_jur_"$file".csv
ftp_to_q_pnet.ksh pur_jur_"$file".csv
compress pur_jur_"$file".csv
mv /home/odbms/prod/cg_batch/purchase_journal/pur_jur_"$file".csv.Z /dataload/odbms/dataout/pur_jur_"$file".$curdt.csv.Z
else
echo No records found for Purchase Journal
rm pur_jur.csv
fi

echo $0 ended at : `date '+%d-%m-%Y %H:%M:%S'`

NAME

       times - shell built-in function to report time usages of the current shell

SYNOPSIS

   sh
       times

   ksh
       times

DESCRIPTION

   sh
       Print the accumulated user and system times for processes run from the shell.

   ksh
       Print the accumulated user and system times for the shell and for processes run from the shell.

       On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:

       1.  Variable assignment lists preceding the command remain in effect when the command completes.

       2.  I/O redirections are processed after variable assignments.

       3.  Errors cause a script that contains them to abort.

       4.  Words,  following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
           able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation  are  not
           performed.
