I've found a way to avoid the problematic POKEGL,PEEK(GL) combination. Furthermore, it allows the line number to be passed as argument with the USR function. We need 6 bytes for a small ML routine, which fits nicely behind the screen memory... :) 100 S=8186:REM S=4602 for +8K RAM expansion, or more ...

@Jeff: Calculated GOTOs are useful, if you have a LOT of jump targets, whose line-numbers follow a regular pattern, say, 300, 400, 500, ..., 1800, 1900,..., and you couldn't put all these in one ON GOTO command. @Rob: This surely won't work directly on a VIC, as the routine alters the USR vector to ...

Lee, I checked the *.zip file, and couldn't find any obvious errors. However, I found the strings somehow difficult to read, as green on white doesn't have a good contrast on the CRT I use. I do use an own program similar to TEXTPORT, but written in C, that checks for repeated runs, and adjacent quo...

Logic errors
Yup. It is really progress. Logic errors however, I have not found any remedy for. I've found quite a simple remedy. I try to refrain from non-obvious code. As I write a piece of code, I always think about what would happen if I were about to extend its functionality. One simple example (this is in...

Of course Boray's solution still makes sense, if I were about to extract certain parts of a file. But apart from Carlsson's one-liner for the whole-file copy, I'd also like to point out, that zero-valued bytes are read as empty strings by GET#! Thus, line 40 should be replaced by: 40 PRINT#3,LEFT$(A...

One obsessed more! You remind me of South Party by Hybris/Nemesis . In the middle, they show a C= 64 demo, that looks quite believable at first, but then ...

Re: HTML Walker
Hi, Boray! From your web-page: [...]HTML codes are stated withing "greater and less than" brackets. I can't write them here as HTML Walker (as well as any web browser) would think that it's a HTML command. So look at this text in a text editor for examples. In the rest of this document, I ...

Memory requirements down to +8K!
I rewrote the engine. It's also a little bit faster now. Colour scheme is now as usual - blue on white background, cyan border. As I write this, the old version hosted is already replaced by the new one. You can use the same link above.
Maybe +8K RAM expansions are more abundant.

I know there is some difference between SEQ and USR, but I never understood exactly what, even after reading the disk drive manual. On the other side, I think I never saw an USR file. USR files could be loaded directly in the RAM of the disc drive, and executed there. I once saw a program *) for th...

VIC Life
This is an implementation of John H. Conway's Game of Life for the VIC. https://dateipfa.de/.Public/denial/images/minigrafik/life_2.png It runs on a 160x192 grid. 8) Requires +8K RAM expansion. Runs on either PAL or NTSC machines. Instructions: [0] / [1] / [{CRSR}] / [CLR HOME]: (re)set cell, cursor...
