count number of fields not using SED or AWK

hi forums

i need help with a little problem i am having.

i need to count the number of fields that are in a saved variable so i can use that number to make a different function work properly.

is there a way of doing this without using SED/AWK?

anything would be greatly appreciated

What is the field separator? Here is an example using ksh and space(s):
Code:
var="hi there how are    you?"
set -A arr $var
echo "var has ${#arr} fields"

the field seperator is a space
(using bash btw)

How about this?

Code:
 
var="hi how are you" 
echo $var | wc -w
