Synopsis:
$midw(<offset> <count> <text>)
Technical:
This function returns the input text, starting at the given word offset,
and not exceeding the total number of words specified. The offset is
counted from 0 (zero).
Practical:
This function operates on words in the same manner that $mid() operates
on characters, returning only a subset of the input word list. This is
probably mostly useful in a script, perhaps to display the partial
contents of a variable.
Returns:
word subset from input list, or nothing if error
Examples:
$midw(2 2 hello there how are you?) returns "how are"
$midw(2 4 hello there how are you?) returns "how are you?"
