Assigning values to an array

The way I've been using arrays currently have been:

Code:
#!/bin/ksh

set -A myArray

myArray[0]=value1
myArray[1]=value2
myArray[2]=value3
myArray[3]=value4

Is there a way I can assign values to an array that will automatically place the value into the next element in the array like:

Code:
myArray=value1
myArray=value2
myArray=value3
myArray=value4

Without doing:

Code:
set -A myArray value1 value2 value3 value4

Because it's hard to follow if you're reading code and you need to manually feed your array 40 values.

Sorry gersh, I edited my post after you posted.
Is there another alternative to set -A myArray value1 value2 value3 value4 ?

well.... you can read the content of the file into an array like so:
Code:
#!/bin/ksh

set -A array $(<y0.txt)

typeset -i i=0;
while (( i < ${#array[*]} ))
do
  echo "${i} -> [${array[$i]}]"
  (( i+= 1 ))
done

Or you can set array cell to values in a loop - something similar to the above.

Write a function:

Code:
$ cat loadr
#! /usr/bin/ksh
function loadr
{
        array[index]=$1
        ((index=index+1))
        return 0
}
index=0
loadr cat
loadr dog
loadr mouse

set | grep array
exit 0

$ ./loadr
array[0]=cat
array[1]=dog
array[2]=mouse
$
