EDIT:
I have it working now, code is below for anyone that it might help. I did what i needed with a nested function.

Code:
#!/bin/ksh
# define array
set -A line_array

# select input file
file_name="cb_list.dat"


# populate the array
i=1

while read file_line
do
   line_array[i]=${file_line}
   let i=${i}+1
done < ${file_name}


#Display selection options
i=1
x=10

var_select ()
{
while [ ${i} -le ${x} ] && [ ${i} -lt ${#line_array[*]} ]
do
 echo
 echo $i ${line_array[i]}
  let i=$i+1
done

#Select an option

    echo
    echo "Select an option number or press enter: \c"
    read num
disp_select
}


disp_select ()
{
if [ ${num} -le ${i} ]
  then
    echo "You have selected: ${line_array[num]}"
else
    x=${x}+10
    var_select
fi
}

var_select


# end

echo

ECHO(1) 						    BSD General Commands Manual 						   ECHO(1)

NAME

     echo -- write arguments to the standard output

SYNOPSIS

     echo [-n] [string ...]

DESCRIPTION

     The echo utility writes any specified operands, separated by single blank (' ') characters and followed by a newline ('
') character, to the
     standard output.

     The following option is available:

     -n    Do not print the trailing newline character.  This may also be achieved by appending 'c' to the end of the string, as is done by iBCS2
	   compatible systems.	Note that this option as well as the effect of 'c' are implementation-defined in IEEE Std 1003.1-2001
	   (``POSIX.1'') as amended by Cor. 1-2002.  Applications aiming for maximum portability are strongly encouraged to use printf(1) to sup-
	   press the newline character.

     Some shells may provide a builtin echo command which is similar or identical to this utility.  Most notably, the builtin echo in sh(1) does
     not accept the -n option.	Consult the builtin(1) manual page.

EXIT STATUS

     The echo utility exits 0 on success, and >0 if an error occurs.

SEE ALSO

     builtin(1), csh(1), printf(1), sh(1)

STANDARDS

     The echo utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'') as amended by Cor. 1-2002.
