twinBASIC Update: May 21, 2023

Highlights include a twinBASIC port of the classic Lemmings PC game, the potential sale of Wayne's MDE conversion service, and a mention in the 8bitnews Newsletter.

twinBASIC Update: May 21, 2023

On April 23, 2021, I helped Wayne Phillips introduce the world to twinBASIC at the Access DevCon Vienna conference.  I boldly predicted that twinBASIC (along with the Monaco editor) would replace VBA and its outdated development environment by 2025.  With that goal in mind, this weekly update is my attempt to keep the project fresh in the minds of the VBA development community.

Every Sunday, I will be providing updates on the status of the project, linking to new articles discussing twinBASIC, and generally trying to increase engagement with the project.  If you come across items that should be included here, tweet me @NoLongerSet or email me at mike at nolongerset dot com.

Here are some links to get involved with the project:


EverythingAccess MDE Conversion Service...For Sale?!?!

If there was any doubt that Wayne is all in on twinBASIC, the following Discord post should put that to rest:

I'm currently contemplating the idea of taking on a full time developer to help progress tB to the next level.  As most of you already know, in the current beta state, the income generated from tB is not yet sufficient to sustain one full time salary.  We're getting there, but not quite there yet.

In order to fund a new developer in the near term, I'm considering options around releasing equity from my other business, EverythingAccess.

My current thinking is that my MDE to MDB (and ACCDE to ACCDB) conversion service is probably the one aspect of the business that would be of most interest to somebody.  It's a service model that works very well, is largely automated, and as such is a nice profitable cash-cow.  If you're not aware of the service, you can read more here:

One untapped potential of the service is that most of the clients that come to me actually want more than just a straight conversion... for example, they often want things like upgrades to support the latest versions of Access (e.g. 32-bit to 64-bit), or to add feature X, but in many cases I have to turn down the additional work, due to my work load on other projects, such as tB.

It's a worldwide unique service.  It's not something that is easily copied, since it requires significant R&D costs to produce.  As such, over the 15 years or so having offered the conversion service, I've been contracted by some of the biggest companies and corporations all over the world.

If you're reading this and would like to know more about the opportunity, or know someone that might be interested, please do get in touch as I'd love to hear from you.

Lemmings. In twinBASIC.  64-bit.  Brought to you by fafalone (who else?)

Here's fafalone's introduction from the Discord show-and-tell channel:

In case you haven't been following the Lemmings thread in the Bugs channel, today's Beta 304 release fixes the remaining issues in Lems64 - my 64bit compatible port of Carles PVs Lems, a remake of the classic Lemmings. It's very, very complex VB graphics work, and shows off tB's astounding level of backwards compatibility even moreso than the API-heavy projects I typically post. Lots of unusual syntax and VB methods in play. If tB is running things like this, nothing is too far off in terms of back compat.

twinBASIC makes an appearance in the "What's Up in Retrocomputing Land" section of 8bitnews Newsletter #78:

BASIC is dead, long live BASIC. In a significant move towards preserving classic code, TwinBASIC, a modern BASIC compiler aiming for complete compatibility with all existing VB6 and VBA code, is making steady progress.

Whose Project is it Anyway?

I've lost count of the number of times people have assumed that twinBASIC is my project because I've presented it on multiple occasions at Access DevCon and I have been writing this weekly update since it launched.  Apparently, I'm not the only one who receives this misplaced credit:

wqweto is a genius. Check out his twinbasic project, 99% similar to VB6 with a bunch of extras, modernising the language. Shout out to all the VB6 legends still going at it and extending the language, wqweto, the trick, olaf, retailcoder.
- HackerNews

Now, I've been following the twinBASIC comments section long enough that I'm not about to dispute that first sentence.  But just to be clear: twinBASIC is the work of primarily one man, Wayne Phillips.

That said, if I had to name a developer other than Wayne who could tackle this project, wqweto (aka, Vladimir Vissoultchev) would be at the top of a very short list.


Here are the updates from the past week.  You can also find this information by visiting the GitHub twinBASIC Releases page.
