Code Snippets Cookbook - 6502 edition

[SyntaxErrorSoft]

Hi all, I apologise if this isn't the proper forum for this!

I've updated my paid Code Snippets Cookbook - 6502 edition. I've added a new chapter on using BBC Micro VDU graphics. It uses Kick Assembler as the assembler for the example; requires JRE (Java Runtime Environment). I hope someone finds it useful.

Well done.
The thing that I think catches some people out when using vdu from assembler is that they forget that vdu is an os feature and whilst there are equivalents to some basic keywords, basic uses vdu but also sometimes does some extra stuff.

You don't compile assembly language code, you assemble assembly language code, compiling is converting non-assembly language code into machine code.

Did I say that somewhere? I'll fix it if you let me know
cheers,

Hi all, I've finally updated my code snippets cookbook (paid version) with another chapter - BBC Micro graphics – VDU graphics!

It includes an example .asm program and how to compile it to a BBC disk image!

I hope you enjoy

Hello and thanks for the effort in writing the book, very appreciated.
In page 4 of the cookbook you say that the indirect jump using RTS uses 4 bytes less respect to the indirect jump: JMP (address)
"It is generally 4 bytes smaller, and 1 cycle slower than the indirect jump, but is less buggy."
But checking the code seems that the RTS jump uses more bytes than the indirect jump.

But isn't that correct in this exact sense? You assemble a program written in assembly language, but you compile together a bunch of different things into a working disk image. One of the things is the actual machine code produced by the assembler, but there's a lot more like maybe a !BOOT file, ...

(But maybe it's just my limited knowledge of english in this case, so please correct me if i'm wrong )

Thanks for the correction, I'll change my wording to something different, like "create a BBC disk image from the example"
