... Also, if NO is installed in IDE0#1 and A2 in IDE0#2, NO boots and A2 gives the black screen. While NO is running, FileSystem.Mount CF AosFS IDE0#2 ~ yields CF: OFSAosFiles: Bad volume size Nothing I've thought of has changed since the installation which gave a working A2. Ideas? ...

Error in access to CF or to filesystem after installing A2.
by peter＠easthope.ca 27 Mar '15

Hi, I've installed A2 to a CF card using an A2.iso built using LinuxAos. Attempting to boot via BootManager gives a black screen. Attempting to mount the CF part from a working Native Oberon gives, "CF: OFSAosFiles: Bad volume size". Attempting to boot via GRUB gives "error: hd2 cannot get C/H/S values". About a month back, a similar installation gave an A2 on a CF which booted up with no problem. Does anyone recognize the failure here? What might I work on to solve it? Thanks, ...

I do 99% of my PC-related Oberon work on Windows 7 using the Gardens Point Component Pascal (i.e. Oberon-2+) compiler. It is still supported by John Gough the author and, as it is a .NET based system it currently works on all current 32-bit and 64-bit versions of Windows and more than likely many new versions yet to come.

Oberon 3 on Windows 7, PELinker, Windows executable
by Dieter 18 Mar '15

18 Mar '15

Hi, I am new to this list, but do have some 20 years experience with Oberon on Windows. Still there are things which I do not fully understand, e.g. PELinker and Oberon debugger. Right now I am working on an application which translates MusicXML (a proprietary language to describe musical notes) into another input language, called PMX, which in turn generates TeX-code for typesetting notes. Is there anywhere out in Cyber Space someone, who could give me a helping hand on how to use PELinker in order to transform an Oberon-Module into a Windows *.exe, so that I can call it from the WIndows command line in the following form: /myprogram.exe "path to input file" "path to output file"/ Thanks and regards, Dieter

I added Dates to then list of modules and then got a similar error message with a different module. Eventually after a bit of trial and error I got it to link with the following module list (the order is important): MODULES Kernel32, Kernel, ADVAPI32, Reals, Registry, Dates, FileDir, AosIO, Files, Modules, Strings, InOut Regards, Chris Chris Burrows CFB Software http://www.cfbsoftware.com

If you have more than one executable Oberon procedure in the Module then you could add a third parameter to your command line. You can then read that parameter and interpret it in your program to decide which executable procedure to call. > Then I tried to extend this in a way that the EXE would read a > parameter from the command line. > Since I do not know the intricacies of the Kernel32-Library, OK - here is a start for you. Kernel32 has a procedure call GetCommandLine that returns the content of the command line that your program was called with. I have extended the HelloCon example to get the command line and display it. Hence, if you call it with the command: Hello abc xyz 123 It will display: Hello from Oberon! Hello abc xyz 123 The source code is: MODULE HelloCon; IMPORT Kernel32; VAR cl: Kernel32.LPSTR; commandLine: ARRAY 255 OF CHAR; BEGIN Kernel32.Str("Hello from Oberon!"); Kernel32.Ln(); cl := Kernel32.GetCommandLine(); Kernel32.CopyString(cl, commandLine); Kernel32.Str(commandLine); Kernel32.Ln(); END HelloCon. The work that you will now have to do is parse that command line to extract the three parameters "abc", "def", "123" as strings and then interpret them according to your requirements. > I tried the following: > The only idea I had was to try to use the parameter mechanism of > Oberon > and hope that this would be magically transferred to the > executable. Unfortunately not. Once you get out of the Oberon environment and into a Windows command line (i.e. MS-DOS) environment then you have to give up all of the GUI capabilities of the Oberon environment. If your program is dependent on any GUI, graphics or mouse capabilities then you need to have a rethink about what you are trying to do. > > A batch solution like << myprogram.exe "path to input file" "path to > output file">> would be sufficient for my present task. Good. That will make your life a whole lot easier. > But could one also produce screen oriented interactive Windows > programs from Oberon code? Yes. If you use a development system that was primarily designed to produce screen oriented interactive MS Windows programs e.g. Blackbox, Gardens Point Component Pascal, POW! etc. Regards, Chris Chris Burrows CFB Software http://www.cfbsoftware.com/gpcp

Depends on the context and your objective. My earlier answer wasn't complete. A non-partitioned store doesn't have an MBR but can be bootable. If a partitioned store has a boot manager working and an OS is being installed to an unused part, the configuration of the boot manager might need adjustment but the MBR shouldn't change. If you are making a complete new multi-boot setup on a store, then something should be written to the MBR. Otherwise use a boot diskette or something more arcane. For a much better answer than I can give, review ocp.inf.ethz.ch/wiki/ and pertinent articles in the Wikipedia. Regards, ...
