Applesoft BASIC

So settling down to programming on the Apple II+, we had several books to help me with the process. Of course there was the standard green covered Applesoft book, and Mr. Alessi also has another book but I can't remember the title. I tried to find a shot of the book cover on Google but no luck.

Before we started writing inventory management software I tried my hand at creating some graphics. The Apple II had hi-res graphics (for that day), and Applesoft had high level commands for drawing so you didn't need to POKE and PEEK as much as in other BASICs. We had only a green phosphor monitor without color, but this was appropriate for business software development.

When editing a program in Applesoft BASIC, you could type some escape sequences to move the cursor around. If you moved the cursor up to the start of a line on the screen you could then reenter the line by moving the cursor to the right, and you could substitute some characters to change the line of code. This was crude compared to the way you did things on a VIC-20 where you just moved the cursor to the line you wanted to edit, changed just what was needed and hit Return.

Also, I had never written software before that used a floppy disk. This was another thing that I needed to become comfortable with. Our Apple II had 3 floppy drives, each was 143K. We also had a 16K card and a Z80 Softcard so the machine could run CP/M, but this was something we rarely did.

My First Programming Job

As well as I can remember (this would have been 1981) I met Patrick A. Alessi when I was 14 years old at NEECO. He was there purchasing an Apple II+ and an Epson MX-100 printer, and he told the sales guy there he needed a programmer to work on some business software. They pointed across the store at me. He told me later that he said, "Who, him? He's just a kid!" They introduced us to each other.

Turns out I knew his son Michael from playing kickball at the park down the street. Mr. Alessi lived a mere 4 blocks away from me, which was the perfect distance. So I began visiting his place. As first we just played pool and experimented with his new Apple II+, and Mr. Alessi made no apologies about sharing his political opinions while smoking different kinds of pipe tobacco.

Since my friend Richard had an Apple II computer I got some games from him, and I made a joystick for the computer out of parts I bought at Radio Shack. I reused the case from an RC car's remote control. I cut out the steering wheel and replaced it with a dual-potentiometer joystick. It was ugly, but I saved some money. ;-)

Mr. Alessi was interested in creating some trend following inventory management software, and he talked a lot about this. Eventually we would begin to write this software, and do a lot of other things as well. This was not going to make me much money in the short run, but I couldn't have asked for a better opportunity to learn.
