Re: Weeknight 'Virtual' Dev session #2, Thursday 10th September 2020, 7pm - 10pm

I'll happily attend. I'm not currently working on anything in particular, but will happily observe.

It might be the only chance I have to attend as the choir I belong to are restarting the following Thursday.

Re: New: in-browser BBC BASIC for SDL 2.0

Would it be possible to load a local file? E.g. appending ?chain=file://blablabla.bbc to the URL. I tried it but nothing seemed to happen.

Also, is the 32k memory limit in place (like in the trial version)?

Re: Picked up some unusual equipment today

Still no photographs, but that's mainly due to spending the last three weeks watching snooker on the telly. I decided to take a look at the tower PC and connections to the "track eye" device. I opened up the tower PC first, and took a look at what is in it. The motherboard is an ASUS board with inte...

Re: Creating a !BOOT file

One thing to watch out for when EXECing a !BOOT file is that the file is left open when the BASIC program CHAINs. Mostly this will not be an issue unless the program does a lot of data file accessing. BASIC can only have 5 simultaneous files open at one time and will crash due to the !BOOT file sti...

Not easily, unless you want to use the BASIC OPENIN, OPENUP, CLOSE etc. commands and write yourself a text file editor.

Install a ROM such as VIEW and you can load that to edit your !BOOT file.
