   You'll find it's very similar in atto! Use the Up/Down arrow keys to go to previous lines, and you'll be able to edit those lines directly. The currently-edited line will be saved when you go to a different line. The dis

   I agree, which is why I have implemented some useful editing features that might make it easier to enter your programs: - Syntax highlighting, to make code easier to read - Typing `edit` followed by the line number, and then pressing Enter,

   Thanks for your feedback! It seems I did miss some instructions about how to break the program on a specific help page in my guide, but I've now mentioned it. Considering that atto is designed to accommodate beginners, I didn't wa

   Agreed, however, programming on mobile isn't the most optimal experience in general. atto was mainly built for the desktop, so I'd suggest you try it out on a computer instead of a phone!

   Unfortunately, all iOS browsers must be WebKit-based due to the limitations imposed on App Store apps. The problem is, WebKit doesn't support regex lookbehind which is an extremely useful feature for tokenising atto programs. Hopefully

   It's mainly regex lookbehind, but there can also be many other side effects of using Safari over Chrome or Firefox (such as page zooming issues and other rendering stuff, and their disappointing lack of good support for PWAs). The rege

   I'd love to see that! There's plenty of graphics commands in atto, so I'm sure it's possible to recreate.

   That's very true; they're definitely the essentials to any BASIC interpreter! `if` is also very useful as well to do conditional jumps, and so is `input`. With those commands, the possibilities are endless!

    The spaces issue should now be fixed (see GH PR #7)! If you do a hard reload, it should be much easier to edit now. `if`/`end` _should_ work; try out this demo to see it in action: https://jamesl.me/atto/?code=10+n

    Should all be fixed now! See https://github.com/James-Livesey/atto/pull/7 for more details. In the end, using `input` still wasn't sufficient to fix the lag, so instead I 'bodged' the delay bef

    Yeah, hopefully am going to get it working again today, so fingers crossed there'll be more fun along the way!

    Nice language! Love the syntax too; quite similar to atto, but with a few unique features which really does make it easy to use!

    Hi there! I'm the creator of this programming language. I've designed this language to resemble the style of the BASIC programming languages of the 80s, but with the modern functionality of today (syntax highlighting, rich editing

    Glad to hear that despite the weird behaviour with Firefox, you enjoy the nostalgia! If it helps, if you want to write really long programs, it's possible to create .atto files in a text editor and then import them into atto by pressin

    Yup, you've pretty much summed up Safari really well there. I've come across sooo many annoyances when supporting Safari that I do wonder how the developers of the Apple website etc. don't get annoyed at the lack of useful su

    It's all there! Try the `import` and `export` commands. Ctrl+O and Ctrl+S work as well, provided that the files end with .atto (unless you set your file open dialog to search for all files). `share` also lets you distribute your code v

    Try using Ctrl+S and Ctrl+O for file save/load. There's `import` and `export` commands as well to do this, and there's even a `share` command to share your code via a URL! eg. https://jamesl.me/atto/?code

    I wanted it to be as lightweight as possible, with only a few support libraries to show the Markdown content for docs etc. It's all done with vanilla HTML/CSS/JS and I put the new JavaScript modules functionality to good use

    You should find it works! Once you type run, the caret will disappear as the program does nothing infinitely. Press Esc to break the program to carry on! But it should be 20 goto 10 if you want to print the same text again and again.

    Thank you! That was exactly what I was opting for — I was looking for a good terminal font for this project which is nice and rounded, and I came across Brass Mono, which seems to fit the job really nicely. Though it unfortunately doesn&#x2

    Interesting! I've just loaded it up on my latest Firefox and I see what you mean -- there's quite a lot of input lag going on there. I mainly develop in Chrome but I've tested this in Firefox before and it was alright. I bett
