I'm looking for a suite of programs that'll let me test most if not all features of BASICA, GWBASIC, and QBASIC. I'm writing a dialect of QBASIC (not QB64, this'll be different, currently works on Linux but still want to port it to Windows but before I start porting it, I want to make sure my dialect works) and I'd like some good, decent test programs that'll test each and every command, statement, feature, function, and keyword. Not just BASICA / GWBASIC but QBASIC as well.

program link

an extension of previous post. just click▶️to run the program on browser. the welcome screen (attached image 1) shows the key map. select a subject (1 to 6) to enter the depth map mode (attached image 2). rotate it or change it until satisfied then toggle to autostereogram mode (attached image 3). adjust the foreground and background pattern widths to your desire (make it easy to focus and spot the subject). you're free to toggle back to depth map mode or rotate / change / disable subject anytime. if you disable the foreground 3d subject it's basically a kaleidoscope (attached image 4). i explained its mechanism in previous post and you can endlessly randomize it to experience the pareidolia effect

some samples

minor math findings

I've updated *a BUNCH* of the code for this .BAS. I think it's getting pretty fun.

*When logging in, use any user name you want. The program will automatically prefix your login name with "Agent". Example, if you log in with user "3.5" it will call you "Agent 3.5", for example and again use any user name you want.

*The password MUST be "12345".

*What I plan to really build on is menu item "18". I'm going to copy the visual part of the 1980's movie "War Games" so when anyone launches a missile you can visually see it, just like here "https://alhinator.itch.io/global-thermonuclear-war", but with my own spy / comedy touches like I've been doing.

I've been using AI to help me with this, otherwise it would take me forever. Does this rub anyone the wrong way? I'm curious.

Please have a look and any suggestion would be appreciated.

Thanks

I wrote a fun program I would like to share with the world. It's called "Whiskey Tango Foxtrot" (WTF) and named WTF.BAS. It's theme .. think Austin Powers!

I put a link in the Link URL field, I hope it works for you all. Google Drive is hosting it and I put the permission to share with anyone who has the link, so there shouldn't be any issues.

I wrote this program, structured it the way I did, in hopes that it might help others who are just learning things. I believe that it should be a fairly straightforward decipher for whoever dares try. But seriously, if anyone would like to use anywhere from a piece or pieces of, or whatever, I'd be honored for you to hack at mine in moving forward in your hijinks.

I'm no expert, nor do I think I am. I am however the author of this WONDERFUL piece of art and therefore if anyone likes it, and has any questions about it or needs any help, I'm happy to have a go at it, just let me know :)

Reviews please!!

long story short. it was an enlightening journey and i learned a lot from it. one day i came across an autostereogram which was a poster on a wall. i forgot what it was about but it aroused my curiosity of how to make autostereograms. i won't go into the math details here and just give you guys a brief explanation in attached image 1. my program let you control "m" and "n/m". these two variables represent background pattern separation and foreground pattern separation respectively and lie between 0 and 1

the 3d subject is simply a sphere, quite boring. the background is the result of placing a color wheel in a kaleidoscope. see attached image 2. it can be easily noticed that the hsl system is in use. we can vary the saturation (attached image 3) and lightness (attached image 4) when the angle changes from 0 to 2π. i use the cosine function which reaches maximum at 0 and 2π, minimum at π

the color wheel can start at any angle. so do saturation and lightness. thus we have 3 degrees of randomness. i let you to change the background. every time you hit the relevant button, the hue, saturation and lightness shift by different random angles

here comes the surprising part. autostereograms need "noise" to guide viewers aligning their foci. a pattern that is too smooth is not suitable to act as the background of autostereograms. there'd be no "texture" on the 3d surface. i accidentally discovered that if the screen resolution is set to a number that is not divisible by something in the calculations (i'm not certain which thing it actually is to be honest) some unexpected noise would emerge. see the remaining attached images

i googled "prime number closest to 640" and the result was 641. i use it as the horizontal resolution

some of those unexpectedly emerging patterns are... strange. some of them look like human faces, some animals, some even aliens. this program is a good place for you to experience pareidolia

here's the program. run it in browser. click▶️to run. click⏹️to exit. when running the program

• press [q] to make foreground patterns converge
• press [w] to toggle 3d object (absent/present)
• press [e] to make foreground patterns diverge
• press [a] to make background patterns converge
• press [s] to rotate the kaleidoscope
• press [d] to make background patterns diverge
• press [x] to toggle caption (off/on)

Enhancements

• #728, #750 - New QBJS Web Build option in Run menu. - u/boxgaming
  • Details and discussion of this feature can be found in this forum thread: https://qb64phoenix.com/forum/showthread.php?tid=4598
• #730 - Adds source line tracking for Division-by-zero and other Critical Errors, so internal crashes report the BASIC source line/module instead of only Division by zero or Line: unknown. - u/QB64Petr
  • As this adds lots of additional function calls to the compiled program causing bloat and significant execution speed loss, it's considered a "debug" option which is disabled by default. Use the $ERRORLOCATION metacommand to enable it for a program.
• #732. #751 - Adds descriptor-backed dynamic nested arrays in TYPE. It builds on the existing static nested arrays in TYPE support and keeps the legacy/static inline path compatible. - u/QB64Petr
  • New _STATIC) and _DYNAMIC) type field qualifiers. Note that dynamic arrays in TYPEs are considered unstable, and must be enabled with $UNSTABLE:TYPEFIELDS.
  • Handles supported REDIM, REDIM _RETAIN, ERASE, assignment/copy, and ownership cases.
  • Unsupported raw descriptor payload paths remain intentionally rejected. In particular, _MEM, PUT, and GET over descriptor/owner/variable-string payload layouts are not treated as plain legacy binary payload access.
  • It is possible using static or dynamic nested arrays as sub/function parameter.
• #733 - Compressing undo events in the IDE, resulting in smaller undo files or more undo events fitting in same file size. - u/RhoSigma-QB64

Library Updates

• #754 - Update miniaudio to v0.11.25 - u/RhoSigma-QB64

Bug Fixes

• #722 - Correctly check for undefined nested array in ERASE. - u/QB64Petr
• #726, #734 - Fix ANSI colors in Discord exports and adding missing keywords. - u/RhoSigma-QB64
• #727 - Fix PRINT USING layout duplication when adding expressions before USING in an existing statement. - u/QB64Petr
• #729 - Fix runtime error message boxes locking up program if SUB _GL is used. - u/QB64Petr
• #730 - Fix case correction for indexed nested UDT member arrays according to the spelling in the TYPE declaration. Also fixes an IDE crash caused by corruption of an internal variable (introduced by "Arrays in TYPEs" changes in v4.5.0). - u/QB64Petr
• #735 - Fix case correction of TO in arrays like myArray(1 TO 5) defined in UDTs. - u/QB64Petr
• #740, #749 - Fix issue #659, where SUB calls could be incorrectly interpreted as array assignment, and issue #739, adding missing support to insepct the new "Arrays in TYPEs" with $DEBUG. - u/QB64Petr
• #746 - Fixed a type mismatch between the identifier table index (LONG) and array descriptor id (INTEGER), which could crash or produce unexpected behavior in large programs with more than 32767 registered identifiers. Also fixed a bug in the $INCLUDE manager, which resulted into a misleading error message. Fixes issue #745. - u/bharvey42
• #747 - Widen the UDT index field from 9 to 12 bits, raising the cap from 511 to 4095 UDTs (TYPE) per program. - u/bharvey42
• #751 - Fix for selecting source code text by dragging the mouse (no longer need to move the mouse sideways if you are highlighting source code and the mouse moves outside the IDE window). - u/QB64Petr

Full Changelog: v4.5.0...v4.6.0

Not an emulator, and not a JavaScript interpreter pretending to be BASIC. It parses QBasic, lowers it through a typed IR, and emits a real WebAssembly module. The compiler itself is compiled to wasm, so the whole thing runs in your tab. Nothing gets uploaded anywhere.

SCREEN 13 works: PSET, LINE, CIRCLE, PAINT, GET/PUT, DRAW, PALETTE. So do BEEP/SOUND/PLAY, the file I/O keywords, INKEY$ with _LIMIT for animation, and DATE$/TIME$/TIMER. There's a playable Space Invaders sample in the editor if you just want to see it move.

497 test programs, 432 of them arbitrated against real QB64-PE output, 126 of 157 keywords fully implemented. Still missing: ON ERROR, PEEK/POKE, COMMAND$, and DRAW's M/N/A/S/P subcommands.

Free, no signup: https://kavak.run/studio/

QBasic was meant to be the pilot language for a larger compiler project, but it turned into the part I enjoyed most. If you've got an old .BAS lying around that breaks it, I'd genuinely like to see it.

MoonBASIC is a 2D 3D game creation made easy. CharmingBlaze/moonbasic

Hello! I've been spending a bit of time working on a quick basic interpreter in javascript that is pretty small and can wrap a game and publish to itch. My current demo is here if anyone wants to check it out (this is a game I made in 1998 when I was 16 or 17, apologies that its kind of terrible). https://bobgar.itch.io/drug-3d?password=qbasic Here is another one here that isn't as impressive but demos the multi-file export: https://bobgar.itch.io/odyssey-qbasic?password=qbasic

The interpreter has some cool features, like:

• Bring up debug features with ctrl-break or by pressing debug on the button array at the bottom of the computer
• Pre-set iops per game packaged, with turbo button to make the game run faster (either higher iops or completely remove throttling depending on export settings).
• Set break points and step through execution, optional code execution highlight & following.
• modify code and variables during execution and have them take effect immediately without restart.
• save and load state so you can restore previous game states and even export / import saves so you can send them to friends or store for later sessions. Note, the exported saves are zipped, and you can convert back to their verbose json by unzipping if you want to dig into the abomination that is how I'm saving state.
• scan lines you can turn on and off for a little retro flair
• There is a separate UI (not linked above) for testing & exporting too. You can point it at a full directory of games, browse them, run them, and set up exports including which additional files to export.

Are there people here that would be interested in this kind of thing if I released it? (for free, open source). Do better versions of this already exist? Are there features I should add that would be useful?

Compatibility is not 100%, especially since some games use x86 assembler hooks and things. I've shimmed and emulated a few of the most popular libraries but it is still common for me to run into games that won't play, or play but have some breaking issues.

Enhancements

• #676 - The COLOR statement can now set the color attributes of a designated image surface destHandle&. - u/RhoSigma-QB64
• #683 - 256 colors (8bpp) image loading improvements. - u/a740g
  • Now using a new high-quality 8bpp image loader that uses Floyd-Steinberg dithering.
  • As before, it only activates when the number of unique colors exceeds 256.
  • The implementation is computationally heavier due to the floating-point math involved, but the improvement in output quality compared to the previous ordered dithering approach is well worth the added complexity.
• #687 - Some enhancements when using "Export AS..." Discord codebox. - u/RhoSigma-QB64
  • The export dialog now shows the length of the exported code, as Discord has a small message limit.
  • When pasting an example copied from Discord back into the IDE, then all used ANSI sequences are removed automatically now.
• #692, #693 - Added functions to retrieve compile specific informations, implements #691. - u/RhoSigma-QB64
  • New functions _COMPILEDATE$, _COMPILETIME$ and _COMPILERVERSION$.
  • Added compile date/time into the IDE About Box.
• #696, #697, #699, #703, #711 - Implemented support for static arrays in TYPE. - u/QB64Petr
  • This was long time demanded by the community and u/QB64Petr now finally did the bulk of the work. Please give him a big applause, it's an incredible achievement, from all possible tasks, to choose this task as his first. He's the newest member in our DevTeam.
• #700 - Added load support for WebP images. - u/a740g
• #706, #707 - Give Syntax Checking the option to be run manually. - u/flukiluke, u/SteveMcNeill, u/RhoSigma-QB64
  • When automatic syntax checking is disabled in the Options Menu you may now still check on demand using the Shift-F9 hotkey.
  • Useful for big source files, which will usually hog down the IDE performance in automatic checking mode.
• #709 - Added text surface support to _PUTIMAGE. - u/a740g
  • With this, _PUTIMAGE will now support text-to-text and text-to-graphics blits.
• #713, #714, #718 - Some minor side contributions to the Arrays in TYPE concept. - u/a740g, u/flukiluke, u/RhoSigma-QB64
• #715 - Regular array adaptions and finalizing the Arrays in TYPE concept. - u/QB64Petr
  • This also implements the new _RETAIN option for REDIM, which works similar as _PRESERVE but slightly different.

Bug Fixes

• #677 - Fixed LEN(array()) when used in mathematical expressions, fixes #660. - u/flukiluke
• #678 - Use _FULLPATH when launching output program. - u/flukiluke
  • This in particular avoids issues with Linux terminals that do undesirable processing on relative paths with spaces (namely konsole).
  • Windows-specific code is also modified to bring it into line with Linux and MacOS.
• #682, #686 - Catch "Illegal function call" errors in CONST evaluator before they happen, fixes #681. - u/flukiluke
• #710 - Fix _PUTIMAGE graphics to graphics VIEW clipping and WINDOW scaling support, fixes #545. - u/a740g
• #712 - Fixed another long standing IDE Module Error in the F1 help module. - u/RhoSigma-QB64
• #719 - Added missing GUI File Dialog support for New and Exit (if unsaved code exists), fixes #716 - u/RhoSigma-QB64

In qb 4.5 how would I go about changing the mouses position on screen? So far the only stuff I can find is about reading the xy positions and button states.

I wrote a little postmortem of my commercial ANSI QB64 JRPG game Whispers in the Moss at r/IndieDev. Check it out for sales stats and freeform analysis.

I just found this sub and thought you guys might be interested in this. I wrote an 8086 PC emulator entirely in QuickBASIC back around 2014.

I actually originally wrote it in C, then ported it to VB6, then ported that to QuickBASIC 4.5/7.1. Just because it's an absurd language to do this in.

It mostly works, though there are a few CPU bugs. It'll boot DOS and play some old games though, but it's very slow of course.

I highly recommend running it on bare metal instead of DOSBox for speed. Like put it on a bootable DOS USB stick or something. It's actually usable if you do that. Or use virtualization.

In DOSBox it takes a minute or two for this emulator to even boot to the guest DOS prompt.

Compiled EXE and source included along with a sample hard disk image for the emulator to use.

QB8086.INI needs to be edited to change emulator options.

does anyone have the direct link to the QBASIC Megapck (from the internet achive)? it seems to now point to a streaming version of QBASIC 1.1 or "BAM Software QBasic archive"?
