Hope this helps

str=data1,data2,data3,data4,data5 ## as many as you want

echo $str|awk -F"," '
BEGIN {
i=0;
}
{
for(i=0;i<NF;i++) {
arr[i] = $i;
printf("%d\n", i);
printf("%s\n", arr[i]);
}
}
END {
}'


For reading strings char by char, you will find multiple awk functions, just have a look at man pages for awk

Using an array in bash...
Code:
#!/usr/bin/bash

var="data1,data2,data3,data4"
eval $(echo $var|awk -v RS=, '{printf "myArray[%d]=%s\n", NR, $1}')

echo Number of elements in array: ${#myArray[*]}
echo First element is: ${myArray[1]}

Or the set built-in in ksh...
Code:
#!/usr/bin/ksh

var="data1,data2,data3,data4"
oldIFS=$IFS
IFS=,
set $var
IFS=$oldIFS

echo Number of positional parameters: $#
echo First parameter is: $1
