ENCYCLOPEDIA COMMODOREA
by Dave Moorman
and Many Others
It all started with the C64 LIST
published last month. This was from an
old issue of LOADSTAR, so I didn't pay
much attention to it. But after
mastering and copying 246, I checked
it out. The print-out was not as clean
and nice as I would have liked.
Then, I had need of a certain ROM
routine that clears a chosen screen
line. This is a handy command I use
from time to time -- but have not
written down anywhere. Besides, when I
write something down, I soon lose the
paper anyway.
What we need is a complete, easy
to use encyclopedia of C-64 POKES,
PEEKS, AND SYSes. So I went through
the texts of C64 LIST I and II and
formatted them for our 38-column
screen. Nicer, but not perfect. One
still must search visually through a
lot of stuff one does not necessarily
want at the moment.
Recently, I discovered a great way
to do hypertext using the scrolling
menu of Mr.Mouse or DotBASIC. The
technique is simple: put the hyper-
text on a line by itself. When clicked
on, examine the resulting W$. If it is
a hyperlink, load and display the
appropriate text file.
So, I broke down the POKES, PEEKS,
and SYSes into single text files and
created an easy to use menu file with
hyperlinks. [Voila!] A great and
powerful encyclopedia! (I am ever
thankful that Jiminy Cricket spelled
out that word on Mickey Mouse Club!)
One thing I wanted to do was offer
intelligable menu names for the
routines. Over the years, I have had a
heck of a time figuring out how to get
the information I wanted from the "on-
line help" feature in Visual Basic. I
spent a month figuring out how to
erase, delete, remove, or otherwise
get rid of a disk file. Who'd have
thought the magic word was "KILL!"
So the items are listed in general
areas (BASIC, ML, etc.) and
alphabetically, using the most
significant word first. And, for a
number of items, I included two or
more menu listings. All the better to
find what you need.
But, as with all such collections
of knowledge, the best way to know
what is available is to look! Check
out each item. You can print it out
with a click on PRINT THIS. Then play
with the code to see how it works.
Most everything is here -- tricks,
tips, ML routines, everything. OK, I
bet I missed some esoteric presto-
digitalizations. YOU can add any that
you want. Use Mr.Edstar to add new
menu items to "e.encyclopedia", that
edit lines 2000-2199 to include the
new filename. Look at the code for the
format.
Then again, who is doing plain old
C-64 programming these days? Who wants
to learn to create great programs on
this old platform? I don't know. I do
know that this encyclopedia is now on
my Utility disk image. Any time I need
to know a certain trick, it is there
in an instant.
