Programming languages

I want to learn ARM assembly

I have Bruce Smith’s book “Assembly Language – Risc OS Beginners”. ⁰ I think it is nice and accessible, but I don’t know how dated it is. I’ll also be honest and admit that I’ve been a little put off from learning it, since it seems very clear that 64bit ARM will be completely incompatible, which will mean that anything I’d write will have a fairly short shelf life. He also has a book called “ARM A32 Assembly Language”, but I don’t know anything about it.

Thanks for the support about learning assembly.
but I’m tired, in pain, and scheduled for overtime next week so don’t expect miracles.

If its of any interest I have two versions of pascal.
Neither crashed hideously on my SA 4.39 RPC but I didn’t do more than double click or run the binary. They are

Cambridge Pascal 1.00 1989
Solent Computer Products

Acorn Soft ISO-Pascal Release 2

So, is Textease Turtle a full real LOGO that you can do real work in, or is it just a toy for kiddies to draws lines with?

Hello Alan, I would like to try your two versions of pascal: I did a bit decades ago on an OU course. I know, nostalgia’s not what it used to be :-)
Cheers Col.

Both the educational and professional editions of TextEase include an implementation of the Logo language. There is a keypad for kiddies to draw lines in a maze with, but equally available is

• a command line for entering immediate commands
• a procedure editor
• variables
• linking procedures to other objects in TextEase (for example, a button in a presentation)

The output is typically graphical (“Pen up” “Pen down”) but it is also possible to select an instrument and play musical notes.

re FORTH language

I have put a copy of the WimpForth interpreter by Martin Laeuter (1996) written for the Archimedes on GitHub
Caret handling problems and a couple of other issues; but otherwise it runs fine on 5.28 these days.
If you wanted to write a new FORTH this would be a neat place to start; as it can meta-compile itself.

I don’t know FORTH beyond 1 1 + . but wf seems to work fine!

armv7 pi2, riscos 5.28

FreePascal would be simple enough to compile, as theoritically you don’t need any external libs that aren’t standard. Just doing make would be enough.

I just got my first Raspberry Pi and going through the steps to install RISCOS. I too want to learn ARM ASM and is the really the only reason why I purchased a Pi; however, not to sure where to start.

I see the following post by DavidS, sorry do not know how to Quote message

RISCOS does not use ASM, but normal ARM apps would? I am a little confused where to start. BBC Basic looks interesting.

Last time I did ASM was on my MOS6502 and that was many many years ago.

@Kid Konami: I think using the Inline Assembler of the built in BBC Basic is the best to start playing with Assembler. The !GCC (contains the gnu assembler) package also would allow you to, but it’s a bit more tricky to get startet. For the Inline Assembler you can find lots of information in the net. Or get a book, e.g. “Raspberry Pi Assembly Language RISC OS Beginners by Bruce Smith”. And if you get stuck just ask here…plenty of people still using Assembler since some decades on Risc OS :-)

I recently wrote my first assembler code, and I found this to be the most useful for me: https://heyrick.eu/armwiki/BBC_BASIC_assembler

@Kuemmel:
Thank you. I appreciate your support and reference to a book. I know starting with ASM will be tough, but I am fascinated with how computers work, and the different chip architectures. Also, I am tired of doing Perl and Python, yet they teach programming, but I feel I am not getting to the hardware enough to understand and to mess around with concepts I want to learn about.

@Alan Adams:
Congrads… I bet it was exciting. Thank you for the link, I will check it!
