Hello CFAJohnson,
Thanks for your reply and apologies for if me email did not made sense, I did not included all of the code because I wanted to focus on the problem I was facing. But let me try and give you a better explaination of the my objective and the issue that I am facing.


1. I have got the following text file (below) the , the columns data are
'Test Day', 'Board', 'Betting Number'.


TEXT FILE
============================================

1 3 02-01-27-28-29-30
0 1 01-31-32-33-34-35
0 1 03-06-09-10-20-21
2 1 05-31-32-33-34-35
2 1 06-07-09-10-20-21
4 1 05-07-08-09-10-25
4 1 01-02-10-11-24-25
4 1 01-02-31-32-33-34
4 1 02-04-31-32-33-34
4 1 06-02-09-10-20-21

2. Consider a ticket system, that can have more that one boards (i.e
betting more than one numbers. So take for example the first line, the
board is 3, which means that one ticket will bet with Lin1, Line2 and
Line 3 Betting Numbers.
The problem I am having is that I cannot get the code to read Line2
and then Line 3 Betting Number because the board in Line 1 is greater
than 1.
The code works fine as it is, it reads each line in the text file and
send the data to another shell script ("$LOTO"/bin/loto_tsim
> /dev/null 2>&1 ) see code below

CODE ===========



Code:
#!/bin/ksh
#set -x

# This program extract data from a text file which holds wagering information for games and use these data as parameters
# for the TSIM (Transaction Simulator), which then generates various combinations of wagers (from the text file) using 
# a vitual terminal (terminal 100)
 

main() 
{
 echo "\nPlease enter the Test Day or 0 for all days: "

     while read line ;

        echo $line | read a b c d
