EDIT - I found it, I am stupid, stupid, stupid, stupid. It was so simple...... Sorry, sorry, sorry. Soloman , I can't remember the last time I used a POKE was (or a PEEK for that matter) since I embarked on a long-overdue migration away from BASIC , and started programming in 6502 Assembly on the &...

So? What went wrong? Your code-snippet looked fine. And the STEP -1 command was fine as well. Pfff. This is a part of a subroutine that shows the suitcases. In the game you have to open an amount of suitcases. The suitcases you opened are removed, so I made them invisible by giving the suitcasenumb...

Either post the complete program which crashes or produce a minimal test case that reproduces this behaviour, then we can look further. The code snippet you show in the screenshot above is incomplete , on its own there is exactly a zero % chance it could crash the BASIC interpreter or even VICE. Ju...

Just discovered another bug, or am I mistaking? I am programming the game "Deal or no deal" (USA). In the Netherlands we have the roots of this television-show. When I programmed a screen where the available briefcases are shown, the VIC (Vice emulator) froze when I choose briefcase 1. The...

looking at the PDF version 1.2 the joystick section seems to have errors Thanks for this! As some of you already know, I am working on an expanded color version with tutorials and such. I welcome any corrections or additions. I own the book and it's tremendous. I use it everytime when I'm programmi...

But now again, I struggle with the end of the program. Again garbage. Always the last line. I do nothing in the zero page, I just program in BASIC. It looks like this in the monitor: https://i.ibb.co/rGNwtV7/garbage.jpg The last programlines are DATA-lines. The last is DATA 6,,5, On location $1C8D y...

I wrote my first text-adventure-game for the unexpanded VIC. I was used to the Commodore <plenty of memory> 64, but now I only had 3581 bytes. :D Pfff, I economized by making a world of only nine places with one-word-commands. Well, it turned out to a simple adventure, but I made the step programmin...

Couldn't find minimon. https://sleepingelephant.com/ipw-web/bulletin/bb/search.php?keywords=MINIMON I found a bin, but I couldn't get it to run. I stuck with VICMON, and I found in the manual the E-command. That's the solution so VICMON doesn't interfere with the BASIC-line of SYS. And it works! ht...

It just happened again. Just a program, nothing special, with a blurred end after the listing. You still remain short of providing a reproducible test case, where a program is corrupted without the known usual suspects as cause (i.e. stray POKEs into zeropage or into the tokenized BASIC program tex...

It just happened again. Just a program, nothing special, with a blurred end after the listing. This is the solution. If your program does not end with an END-statement - $80 - (because of subroutines or DATA), add a REM THIS IS THE END after the last line. Attacht the VICMON-cartridge, start VICMON ...

In the Netherlands there is no need for Dutch manuals. Every Dutchman learns English thouroughly at school.

Source is attached. The ZIP file contains the source, the graphics, and a .prg ready to run. smilebounce2.png Very nice. Thank you for attaching the assembler source too. I am a beginning assembler VIC-20 programmer, so I can see how you programmed it. I am using the SYS-method. Before I start prog...

Very nice to see how things are going at the other side of the ocean! And I like the retro-homepage.

I continue with writing a program that calculates the matches after the group-phase. But I do that for myself. Now, this topic ends with this, because I doubt whether this topic is a contribution to this forum. (In America soccer is not something that reaches the front pages of newspapers, so I unde...

All programs on the disk for the unexpanded VIC And hereby the disk with the programs. It's a pity I had to used the normal INPUT-statement. There was no room for my INPUT-routine. Technical description follows later. The disk has the following programs: EURO24-MATCHES To lookup the matches from a s...
