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

locale::codes::langfam

Locale::Codes::LangFam(3)				User Contributed Perl Documentation				 Locale::Codes::LangFam(3)

NAME

       Locale::Codes::LangFam - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangFam;

	  $lext = code2langfam('apa');		       # $lext gets 'Apache languages'
	  $code = langfam2code('Apache languages');    # $code gets 'apa'

	  @codes   = all_langfam_codes();
	  @names   = all_langfam_names();

DESCRIPTION

       The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in
       ISO 639-5.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5
       language family codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a
       constant that is automatically exported by this module.

       For example, the two are equivalent:

	  $lext = code2langfam('apa','alpha');
	  $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages.

	   This is the default code set.

ROUTINES

       code2langfam ( CODE [,CODESET] )
       langfam2code ( NAME [,CODESET] )
       langfam_code2code ( CODE ,CODESET ,CODESET2 )
       all_langfam_codes ( [CODESET] )
       all_langfam_names ( [CODESET] )
       Locale::Codes::LangFam::rename_langfam  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangFam::add_langfam  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangFam::delete_langfam  ( CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangFam::delete_langfam_alias  ( NAME )
       Locale::Codes::LangFam::rename_langfam_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::delete_langfam_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
