That's cheating isn't it ?  r.p.n is a doddle to code :)

If you are doing this in Pascal (First in your newsgroups line) then check
out SWAG, which has several infix parsers (how you write math. expressions
in your code).

SWAG is big though, but it is a superlative programming resource.  It is
accessible from the clpb mini-FAQ (sorry, con't remember the swag url)
that FAQ is also on the Web at:
