I think most full-time programmers will end up wanting to install a full development environment like Lazarus, but the easy zips let you avoid that until later. Yep. Of course, the Lazarus IDE is the tool of choice for fpc programmers. In your original message you wrote: The project I have in mind does not need to have a GUI (nor any Android binding). Yep. I would use Lazarus just as an IDE. Preferably running it on the PC as a cross development tool. But regarding the rather high versatility of the BBB (Beagle Bone black, greatly advanced vs the white thingy), it might be a good idea to run Lazarus on the target, too. I was the (main) TurboPower TPX person for AsyncPro for the last 5 years TurboPower was in business (1998 - 2003), GREAT! We (company) bought an AsyncPro license many years ago, and very happily use it since then. I would be _delighted_to be able to using it on Linux with Lazarus fpc. Especially with non-GUI Projects, which is not that easy because of the reduced Thread communication support in the LCL when no GUI binding is not selected. In this and many other forums I found lots of requests for a decent serial- and Socket- communication unit, that frees the application programmer from the low level thread handling. But, no, I haven't ported it to Linux. I'm using Synapse for that: www.CtrlTerm.com I also use Synapse for this right now. But AsyncPro is a lot more advanced, especially because of the automatic background threads it uses and because of the unified API for serial and socket handling. Thus porting APO to Lazarus/Linux/noGUI would be a GGRREEAATT advantage :-) .

What I'm trying to do is implement some special 8-bit codepage mapping for programs run inside a window, but it would be desirable to be able to run a (unix) shell and a standard editor such as vi. I'm interested in a terminal LCL control as well. Please specify: do you want a terminal (e.g. VT-52) or a shell window? I think it's necessary to separate shell (e.g. Bash on Linux) and window for the purpose of discussion. The interesting case there is where a shell running in e.g. Xterm or Konsole, which normally appends output to the last line and scrolls, switches to running a text editor such as Vi where scrolling is inhibited. There's also the issue of keeping the environment variables that tell a child process the window size (in character units) up to date, and sending a WINCH signal when appropriate. Once there's a control that can handle character-addressable output (and ideally can scroll as well), implementing VT-100 (or -52, or 3270, or whatever legacy command set one's lumbered with) is comparatively simple. It also depends somewhat on the underlying communications mechanism, i.e. serial, telnet, tn3270 or whatever turns you on. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

The reason is that the field ScrollCode of the TWMScroll record always contains 0 (windows 64 bit). Due to a change in the size of lparam and wparam in windows 64 bit the TWMScroll record - defined in FPC's messages.inc - does no longer fit. You will find the correct definition in the TLMScroll record in the LCL LMessages unit. The LCL itself uses the TLMScroll record and the messages LM_HSCROLL and LM_VSCROLL as you can see in TCustomScrollBar (stdctrls.pp).
