Thanks Scott. This works like charm! 1 question as part of my understanding. The line
Code:
eval ${1}_file_array[\${#${1}_file_array[@]}]="$line"

will also the initialize the array?

Updating the post with the results. I just ran the code below and I am getting faulty values as the array is not initialized/set to NULL.

Code:
Code:
CreateArray()
{

  echo "\n Please enter tables that are affected in '<DBName>.<Tablename(s)>' format      :\n"

  i=0
  while read line; do
    if [ ${#line} -gt 0 ]; then
      eval ${1}_file_array[\${#${1}_file_array[@]}]="$line"
      eval ${1}_db_array[\${#${1}_db_array[@]}]="${line%.*}"
      eval ${1}_table_array[\${#${1}_table_array[@]}]="${line#*.}"
      i=$((i + 1))
    fi
  done
  eval ${1}_count=$i
  return $i
}

CreateArray src
j=0;
while [ $j -lt src_count ]
do
    echo " ${src_table_array[$j]}_unload.scrpt"
    j=`expr $j + 1`
done


CreateArray src

j=0;
while [ $j -lt src_count ]
do
    echo " ${src_table_array[$j]}_unload.scrpt"
    j=`expr $j + 1`
done

Output:
Code:
 Please enter tables that are affected in '<DBName>.<Tablename(s)>' format      :

DB1.TABLE1
DB2.TABLE2
DB3.TABLE3
DB4.TABLE4
DB5.TABLE5
 TABLE1_unload.scrpt
 TABLE2_unload.scrpt
 TABLE3_unload.scrpt
 TABLE4_unload.scrpt
 TABLE5_unload.scrpt

 Please enter tables that are affected in '<DBName>.<Tablename(s)>' format      :

DB3.TABLE3
DB4.TABLE4
 TABLE1_unload.scrpt
 TABLE2_unload.scrpt

I tried adding the below lines, to the first of the function, to initialize the array but that did not work too!

Code:
  set -A eval ${1}_file_array NULL;
  set -A eval ${1}_db_array NULL;
  set -A eval ${1}_table_array NULL;

Let me know if I am missing something
