Thanks, Antoni, and to everyone else who helped out with this question. We've had a lot of really great replies, and also really great information. It's been a very interesting conversation.

I thought everyone might be interested in a free ebook that I found at the following site:

http://www.ethanwiner.com[url]. It's called, "PC Magazine's BASIC Techniques and Utilities," by Ethan Winer. The whole book can be downloaded free (475 pages), in PDF format. The book covers the whole history of QuickBasic, way back to BASCOM 1.0, and that history should answer everyone's questions (I hope).

Here's a quote from the Introduction: "Although the emphasis here is on Microsoft QuickBASIC and the BASIC professional Development System (PDS), much of the information will apply to other BASIC compilers such as Power Basic from Spectra Publishing."

I've only had time to read through the intro so far, but it looks like a really good book. Of course, it might be too basic for some of you guys, but I hope someone will find it helpful.

One more question from me: Does anyone know if BASIC PDS can be downloaded free? I've searched, but I haven't found any downloads that are free? I'd really appreciate it if anyone could tell me whether or not this is freeware, and if so, please let me know where I can download it from.

Thanks again, to everyone who contributed to the original question. It was great!

Regards,

Anthony
