XOR is certainly a reasonable and useful thing to want. Have you
filed a feature request to which people can sign on?
Or:
if a <> b then
??? just as good eh? Takes 1 less keyword :)
Not only that, it is really the true meaning of XOR in Boolean logic.
The problem in hardware gates on TTL or CMos was that And, Or and Not
gates only solved certain problems. The Exclusive Or (XOR) gate
easily solved the a<>b problem. It was still possible using the other
gates but it required more complicated wiring. The development of the
XOR gate meant all Boolean equations could be wired easier with
different combinations of these four basic types of gates.
At first I wondered why there was no XOR comparison however I had
been using a<>b all along. It's also amazing how simplifying a
problem to its basics can help one understand programming and improve
its creation in general.
In all, I would like to state that I have always considered the
engineers at RS able to find the simplest and most understandable way
to create code for its users.
There are some that wish to add code shortcuts from other languages
but many of these break the link to the B.A.S.I.C. concept that
REALbasic started with.
Now, if only their documentation could follow suit... :)
