That was the only programming environment (CA-Clipper) I knew at the time. VB6 was a thing, but I had some GUI-antipathy, coming from the older, "purer?" world of DOS. Also POS terminals needed first-class keyboard accessibility. SQL wasn't welcome either - you had to give up the fine grained control of row-level cursors in the flat-file xBase database and use a rather unwieldy looking language.

I would still love to go back to the ergonomics of building user interfaces in DOS. No mouse, no events, no callbacks - just straight imperative programming where everything, including user input, blocks. Nothing async - even network communication was thru Novell Netware file writes, using shared locks. And a single screen to design: 25 rows and 80 columns, and just 16 colors.

After doing GUI work for many years after DOS, thru VB6, jQuery DOM manipulation, Angular etc., ReasonReact and Hooks are the closest I've come to recapturing the ease of building UIs again. I'm also looking forward to trying out concur one of these days (https://github.com/ajnsit/concur-documentation/blob/master/R...) -- it is a Haskell GUI library that lets you do evented handling in an imperative-looking manner.




Well, if you would be using Turbo Vision, then there was mouse, callbacks, events, the whole stuff. And async would just be a couple of chained interrupts.

I also used CA-Clipper, Summer '87 and the OOP variants 5.x.

Most of the stuff did use a mouse and some TUI navigation, with menus and stuff, we had a couple of libraries for it.

Now doing those forms it was pretty neat.


I had a pascal turbo vision accounts app. The client decided to share the data between two machines over a 10baseT network. With the exception of an occasional, but fully recoverable write issue (the user just had to retry their last save operation), I didn't have to lift a finger to get it past y2k. Mouse, printer (serial and parallel) were no problems. Good times.


Good times indeed!


Yeah I used to look longingly at Turbo Vision GUIs, but C++ was scary at the time. Do you think building TUIs with TV was qualitatively better than approaches popular today? Any insights why?


I used Turbo Pascal's variant of Turbo Vision.

As for building TUIs not really, other than the usual Clipper entry forms.

For example, when I moved from Turbo Vision (MS-DOS) into Object Windows Library (Turbo Pascal for Windows 1.5) I did not regret it.

One thing I do conceed, a full keyboard experience is much better for data entry forms and on GUIs the mouse is given too much focus, although the same approach could be easily implemented as on TUIs.


Nice to hear that!
