Help with bad disk

I have a disk which i can get a directory from but of the 5 listed programs I'm only able to copy 1, clearly the disk is damaged in some way. If the data is corrupt then there's probably not much I can do, but is it possible that some kind of cleaning might help, and if so how would I do this? The d...

Re: BBC Basic Assembler

OK, so I got done what I wanted :D In BASIC when displaying a character you can have a foreground colour and a background colour, but the VDP lets you display 2 different colours per character line and not just per whole character. So I've written a small rountine in assembler so you can do this, wh...

Re: BBC Basic Assembler

Yes, I think it also works like that - I need to do a bit more reading.

Re: BBC Basic Assembler

I thought you could use this to throw in a bit of assembler to speed up certain areas of your basic programme but that's not how it works. It's simply an assembler. So you need to assemble your code and save it then load it into your BASIC programme and use the USR command to run the code you wrote ...

Re: BBC Basic Assembler

I thought I'd tried this earlier but I must have done it wrong. You are both right. The left and right arrows are transformed into square brackets in the special 80 col font, they can also be used instead of square brackets in BBC BASIC. So I now have access to the inline assemble in BBC BASIC :) Th...

Re: BBC Basic Assembler

chr$(91)+(93) give left arrow and right arrow not square brackets.

I've printed all ascii on the screen and there's no square brackets.

Also, you can't edit in the same way as u do with xtal BASIC, you need to use the edit command to do a line at a time.

Re: BBC Basic Assembler

In my attempt to find a way of displaying a square bracket I stumbled across this: 20221021_220553[1].jpg Every gfx character has an associated command in BBC BASIC. I may have missed it but I couldn't find a reference to it in the manual, is this a known thing? Will be great for creating 10 liners:...

BBC Basic Assembler

According to the manual you use square brackets to enter/exit an assembler routine, but the Einstein doesn't have square brackets???

Anyone know how to do this?
