| + | ======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:====== | ||
| + | <file> | ||
| + | $numwords(hello there bob) returns 3 | ||
| + | $numwords() returns 0 | ||
