Shell Programming and Scripting

What is a good way to iterate through a variable that has values seperated by a comma?
I thought about converting the commas to spaces, but that sounds inefficent to me. I am using KSH for my shell script. Thank you for any input you can provide.

For example:

Code:

X=55,22,34,61,18
for i in `echo $X | nawk -F , ....`; do
     myfunction $i
done

maybe:

Code:

X=55,22,34,61,18
IFS=,
for i in `echo $X`
     myfunction $i
done
IFS=" "

x=55,22,34,61,18
y=`echo $x|awk -F"," '{print NF}'`

i=1
while [ $i -le $y ]
do
val=`echo $x| cut -d ',' -f$i`
myfunction $val
i=`expr $i + 1`
done

I'd say it depends on how you get the values of x, and how you process those values.
Without knowing how you get those values nor the full scope of what you are trying to accomplish, I'd say, probably you should look into making x an array, rather than just a variable.
