Perhaps a bit late to the party, but I noticed this post and felt it might be of interest to you and others.
Basic is by no means dead, nor is it in the realm of the limited and unstructured language it was back then. Yes I was tinkering with the BASICs back in those days too and have continued over the years. For those looking for modern versions, there is a number of alternatives that people might find useful or interesting, though some I find better than others.
[url]powerbasic.com[/url] - PowerBasic is a commercial program and was written by the late Bob Zale, who also wrote 'Turbo Basic' (originally ZBasic) back in the day, which Borland later bought. Powerbasic comes in two main types for Win, as well as the old DOS version of Powerbasic. PBCC is a Console compiler version for Windows that is very similar to QBASIC and PBWIN, which is a GUI type language. I've used PBCC for years and it's my main programming language, it's fast, small and is certainly not your old BASIC-A. Bob Zale passed away some years back, but another company (that relied on PB) bought it out around 2016/2017 I think and hopefully will continue to develop it.https://www.freebasic.net/
