Does anyone have an algorithm in Pascal that sorts names/words 
alphabetically?  I would like one that does items that are three (3) words 
in length, such as 'Firstname Middlename Lastname.'  It may be a simple 
algorithm but being a programmer who has not done much programming, I have 
not figured it out yet.
                Thanks in advance.

I assume you are using a record to hold the names and I assume you want it
sorted by last name? Basically just get a sorting algorithm out of any book
and do the comparison test on the lastname element of the record, but then
swap the entire record with another if the algorithm calls for it. Having
an array of this record type is also useful. There are so many sorting
algorithms out there and alot of books flat out give you the coding for some
of them. If your library has the book titled PASCAL by Koffman that has lots
of examples on sorting algorithms.
