Handling parameters in Shell Functions

Hi,

Please help me with the below situation where I have to handle the parameters passed to a function in a unique way.

Below is the code, which I am trying to execute. I basically want to pass the parameter to a function, where I am trying to get user input into array(s). I want to name the array(s) based on the parameter. Please help me do it!!

Code:
 
#! /bin/sh
 
#GET_TABLE FUNCTION
get_table()
{
  i=0;
 
  set -A $1_file_array NULL;
  set -A $1_db_array NULL;
  set -A $1_table_array NULL;
 
  echo " Please enter tables that are affected in '<DBName>.<Tablename(s)>' format      :"
 
  while read file
  do
    if [ ${#file} -gt 0 ]; then
      $1_file_array[$i]=$file
      $1_db_array[$i]=${file%.*}
      $1_table_array[$i]=${file#*.}
      i=`expr $i + 1`
    fi
  done
  $1_count=${#$1_file_array[@]}
  return $1_count
}
 
# CALL FUNCTION GET_TABLE WITH 'SRC' AS PARM
get_table src
 
# DISPLAY THE LOADED ARRAY
j=0;
src_count=$?
while [ $j -lt src_count ]
do
# BELOW ARE THE ARRAY NAMES I WISH TO SEE
    echo "File: ${src_file_array[$j]}"
    echo "DB: ${src_db_array[$j]}"
    echo "Table: ${src_table_array[$j]}"
    j=`expr $j + 1`
done

Please let me know for any questions.

Thanks
Bharath
