- 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
