Hallo allesamt, ich habe nach vielen Jahre zurück zu GFA Basic gefunden - die Sprache hat mich nie losgelassen. Jetzt frage ich mich nur: Wie ist der rechtliche Status von GFA? Ist es inzwischen Open Source? Kann man Programme, die man mit GFA Basic schreibt, kommerziell vertreiben? Gibt es hier Erfahrungswerte? Beste Grüße, stratos
Firstly, sorry, but my German is not good, so I shall have to reply in English.
GFABasic is officially abandonware which, legally, puts it in a grey area. That said, I am unaware of any prosecution brought by the original GFA team against any software developer in the last 15 years, nor of any brought against Sjouke Hamstra who has made changes to the code in the form of bug fixes since at least 2005 (see his blog) and has been its main distributor since then.
I am sorry if this is a bit vague. For a fuller answer, contact Sjouke on the contact details on his blog. Alternatively, or as well, you can ask subscribers to the Mailing List, many of whom are German speakers.
After my last reply, I suddenly remembered reading the following on Sjouke's old blog page:
Use GFA-BASIC 32 freely now! GFA-BASIC for Windows 32-bits is now abandonware. Back in 2001 the firm responsible for 15 years of GFA-BASIC products went bankrupt. Despite several pleas for providing the source code to the public domain, no former employee of Gfa Software Technologies GmbH responded to the GFA-BASIC community. This site is dedicated to GFA-BASIC (32) and we will support GFA-BASIC 32 as long as possible. This means fixing bugs and providing the means to use GFA-BASIC 32 on the new OS platforms (Vista/ Windows 7).
I do not have a copy of the original licence agreement issued by GFA but I would be surprised if anything more than an acknowledgement would be required for anything but a large scale distribution - I know that Miscrosoft does not charge royalties for programs written in VB.Net, etc.
