Synopsis:
$numwords(<word list>)
Technical:
This function serves as a replacement for the $#var notation when you
want to count the words in a string not held in a variable.
Practical:
This function is used to count the number of words in an arbitrary
string. Normally, you could get this value with the $#var form, but
that doesn't work for parameter expandos or function return values.
Returns:
number of words in given string
Examples:
$numwords(hello there bob) returns 3
$numwords() returns 0
