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

Error Handling Classes(3)                                              Coin                                              Error Handling Classes(3)

NAME

       Error Handling Classes -

   Classes
       class SoDebugError
           The SoDebugError class is the internal debugging message passing mechanism.

       This class basically serves two purposes: "
   class SoError
       The SoError class is the base class for all the error handling classes.

       The default error handler just prints messages on the standard error output channel, but this can be overridden by client applications. "
   class SoMemoryError
       The SoMemoryError class is used to inform of problems with memory allocation.

       Modern operating systems takes care of handling most out of memory conditions for you, but in certain situations it can be wise to do some
       manual checking and intervention. This class is provided as an aid to help out in these situations. "
   class SoReadError
       The SoReadError class is used during model import operations.

       During model file import, this class will be used to output any error or warning messages. "

Detailed Description
       The error classes are static classes that contain a callback pointer for handling errors of the given type. Coin has default handlers for
       displaying all the types, but these can be overridden by applications by setting other callbacks.
