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

array_rand

ARRAY_RAND(3)								 1							     ARRAY_RAND(3)

array_rand - Pick one or more random entries out of an array

SYNOPSIS

       mixed array_rand (array	$array, [int  $num = 1])

DESCRIPTION

	Picks one or more random entries out of an array, and returns the key (or keys) of the random entries.

PARAMETERS

	      o $array
		- The input array.

	      o $num
		- Specifies how many entries should be picked.

RETURN VALUES

	When  picking  only  one  entry,  array_rand(3)  returns the key for a random entry. Otherwise, an array of keys for the random entries is
       returned. This is done so that random keys can be picked from the array as well as random values. Trying to pick more elements  than  there
       are in the array will result in an E_WARNING level error, and NULL will be returned.
