Jay Versluis I’ve recently discovered a tweet that showed a Commodore 64C complete with green monitor and 1541-II drive, heavily dust covered, but still working and being used in a Polish Auto Shop. The picture itself was fascinating enough, but I’ve also discovered that it was a screen grab from a video – which I’m including here … Read more
In this screencast I’ll show you how to write your own INPUT routine in Commodore BASIC. This comes in handy when you want to reject certain keys from being used when asking users for keyboard input. In my example I’m going to allow all alpha characters (A-Z), as well as SPACE, RETURN and the DELETE … Read more
In this screencast I’ll show you how to add images to your GitHub Readme files. You can use the Markdown or HTML syntax for this, I’ll show you both versions. Make sure to upload images to your own repository and provide the relative path to them. Here’s the syntax: In Markdown In Markdown syntax, use … Read more
A few years ago, when Plesk started supporting Extensions, I gave a talk together with Any Kugaevskiy from at Parallels Summit in New Orleans. My part was about how to get started with Plesk Extensions in general. As a demo project, I removed the big blue promo box in Plesk Service Provider View – and … Read more
When parameters for a subscription in Plesk have been modified, Plesk may lock them. This means that when a change is made to the service plan itself, locked subscriptions are not updated by default. To unlock subscriptions and re-integrate them into the service plan, head over to the subscription in question (from the Subscriptions list … Read more
In this episode I’ll show you how to create the iconic flashing borders on Commodore machines. Back in the day, when the system was loading, this was a nice way to indicate that the computer is busy doing something rather than being dead. I’ll show you the principle both in BASIC and in Machine Language … Read more
In this episode I’ll demonstrate how to use programmatic loops in Commodore BASIC. I’ll show you how to use the FOR/NEXT loop (available in all versions of Commodore BASIC), as well as the DO/WHILE loops (available on the Plus/4 and C128). Enjoy! https://wpguru.co.uk/wp-content/uploads/2018/08/Loops-in-Commodore-BASIC.mp3Podcast: Download (Duration: 11:33 — 10.6MB)
In this episode I’ll explain the concept of Flow Control in Commodore BASIC. It’s kind of a video update of a post I did a while ago. In essence, it means that we can tell the programme to take a different route in the code depending on a condition that’s met. We’ll explore the IF/THEN … Read more
