I downloaded it. After reading the release notes, it is apparent that Turbo51 Studio took a lot of work. And it seems interesting in comparison to other ones, offered for free, that I heard of and installed.

Although the first language I learnt (at the university, about 37 years ago) was Fortran then I shifted to C after I was able buying the BorlandC 3.1 package, I will have now the opportunity to learn, to some extent, Pascal. I use writing all my firmware in assembly to get the most of the old MCUs which are the only ones available in the local market, mainly on these days, economically speaking (before year 2010, I was allowed to buy new MCUs from China for my small private business).

Thank you for your help.
