WORD$( stringExpression, n [,string delimiter] )

This function returns the nth word in the string, string variable or string expression, stringExpression.  The leading and trailing spaces are stripped from stringExpression and then by default it is broken down into 'words' at the remaining spaces inside.  If n is less than 1 or greater than the number of words in stringExpression, then "" is returned.  The string delimiter is optional.  When it is not used, the space character is the delimiter.
