Putting It To Work
Having exercised these capabilities and knowing that they work, now what good
are they?
Well, to users who need the special versions for their own purposes, the answer is
obvious. Also, unlike what often happens when extra features are added, there are
few Disadvantages.
Since each character is assigned an ASCII number, everything we've learned about
computer programming is still valid. In actual practice, the special characters will
be used primarily for report headings, and in word processor generated
correspondence.
We can however compare any special character against any other character, or
against itself. Since BASIC is an ENGLISH-language programming language, they
will probably rarely be used in that way, but each character can even be used as a
variable. It's just like the character it replaced with the same ASCII number.
APPENDIX C contains a summary of the switch settings we just exercised.
