- To quote Charles Needam, "I LOVE
- this stuff!" For over a decade, I have
- been pondering why the C-64 holds me
- in such fascination. What is it about
- this antique, obsolete, limited, and
- sometimes cranky platform that keeps
- me coming back?
-
- The answer is that ever since I
- bought a book on BASIC (before even
- having a computer of my own) I have
- loved the challenge of programming.
- Here is the Great Logic problem, yet
- also a medium of Art. As a pastor, I
- am sure that manipulating bits and
- bytes is better than manipulating
- people. Besides, the bits and bytes
- don't have Pulpit Committee meetings
- to seek a new pastor!
-
- And here I must especially thank
- Robin Harbron, who is not on my Pulpit
- Committee! He does the beta testing of
- each issue. (OK, most issues. Those
- with blatant spelling errors are the
- ones that we rushed out and Robin did
- not check.) Besides giving me a heads-
- up on typos and crummy grammar, Robin
- bangs around on each program to see if
- it works as advertised. This month, he
- found some pesky bugs -- and gave me
- yet another challenge!
-
- Programming is a matter of
- building a repertoire of working
- routines. When "Guerilla" refused to
- Return to LOADSTAR, and gave Robin
- several different errors on different
- tries, I had to figure out that Cleve
- used an IRQ wedge in the program.
- When the code to which the wedge
- points is over-written by other code,
- the machine crashes. The answer was a
- 13 byte ML patch that returns the IRQ
- vector to where it is supposed to be.
-
- We have some truly new software
- this month. Lenard Roach sent in "The
- Envelope Addressor", and I hurried to
- get it on this issue. Here is what
- happens when someone sees a need and
- fills it -- if only for himself. BASIC
- 2.0 can do anything you normally need
- to do -- the way you want it done!
- Take a look at Lenard's code. It is
- clean and well organized and does
- exactly what is needed. The only
- tweaking I did was to make the program
- work on any drive, and add the Return
- to LOADSTAR code -- a simple job that
- made me feel important!
-
- We have a lot of graphics on this
- issue for your entertainment. Andrew
- Roberts sent JPGs of his visit to
- Scotland, which I turned into our own
- SHP files and put in CLIPS. Andrew
- looked at the result and sent a
- description of the pictures -- so you
- can enjoy the trip as well. The King
- Kong presentation came from the web
- -- and was just too much fun to pass
- up.
-
- Next issue, we have a new
- frame-based motion picture system to
- unveil -- and over the next several
- issues will add features and tools.
- Yes, Virginia, the C-64 can do
- movies. Within limits, of course.
-
- If you have some programming to
- do, do it on your C-64 (or VICE) and
- send it in. The money is lousy or
- non-existant these days, but you can
- get a bunch of free software and back
- issues as your reward. Take a look at
- the DotBASIC tutorials on this issue,
- and see how easy writing a program can
- be!
