Hi.

You don't need to initialise an array in shell before you use it.

Code:
eval ${1}_file_array[\${#${1}_file_array[@]}]="$line"

This will set the element of the current count in the array to the value of $line

ie.
Code:
$ echo ${#src[@]}
0

$ src[${#src[@]}]=hello

$ echo ${#src[@]}
1

$ echo ${src[0]}
hello

$ src[${#src[@]}]=world

$ echo ${#src[@]}
2

$ echo ${src[1]}
world

There's no way out of your loop. I've added two lines below:
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))
    else       # added this
      break    # added this
    fi
  done
  eval ${1}_count=$i
  return $i
}

If I type in:
Code:
DB1.TABLE1
DB2.TABLE2
DB3.TABLE3
DB4.TABLE4
DB5.TABLE5

I get the output:
Code:
 TABLE1_unload.scrpt
 TABLE2_unload.scrpt
 TABLE3_unload.scrpt
 TABLE4_unload.scrpt
 TABLE5_unload.scrpt

This is what I'd expect to see. If it's wrong then please post exactly what you typed in, and exactly what output your expect.

mlib_imageerode4

mlib_ImageErode4(3MLIB) 				    mediaLib Library Functions					   mlib_ImageErode4(3MLIB)

NAME

       mlib_ImageErode4 - four neighbor erode

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_ImageErode4(mlib_image *dst, const mlib_image *src);

DESCRIPTION

       The  mlib_ImageErode4()	function  performs  an erode operation on an image by using each pixel's four orthogonal neighbors. The source and
       destination images must be single-channel images. The data type can be MLIB_BIT, MLIB_SHORT, MLIB_USHORT, or MLIB_INT.

       For 4-neighbor binary images, it uses the following equation:

	 dst[x][y][0] = AND{ src[x][y][0],
			     src[x-1][y][0], src[x+1][y][0],
			     src[x][y-1][0], src[x][y+1][0] }

       For 4-neighbor grayscale images, it uses the following equation:

	 dst[x][y][0] = MIN{ src[x][y][0],
			     src[x-1][y][0], src[x+1][y][0],
			     src[x][y-1][0], src[x][y+1][0] }

       where x = 1, ..., w-2; y = 1, ..., h-2.

PARAMETERS

       The function takes the following arguments:

       dst    Pointer to destination image.

       src    Pointer to source image.

RETURN VALUES

       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
