Short: Oberon System V4 for Amiga V1.3 Author: degner@pallas.amp.uni-hannover.de (Stefan Ludwig, Claudio Nieder, Ralf Degner) Uploader: degner@pallas.amp.uni-hannover.de (Ralf Degner) Type: dev/obero This is the V1.3 release of "Oberon System V4 for Amiga" (O4A) of ETH Zurich. "Oberon System V4 for Amiga" requires at least an MC68020 and a minimum of 1.2MByte of free memory (2.5 MByte recommended). Floating point calculations (types REAL and LONGREAL) additionally require a FPU. This version requires WB2.0 or better. A screen mode requester will be available only with asl.library V38 and higher. "Oberon System V4 for Amiga" works best with 16 colors (4 planes) and high resolutions (1024*768 or higher). The StartUp-Script will test your system and will report problems. NOTE: Oberon for Amiga doesn't work on XFH file systems. "Oberon System V4 for Amiga" is distributed as an lha archive. A directory will be created if you extract it. O4A is started using the Oberon icon. Additional archives: Oberon-NonFPU.lha - to use O4A without FPU Oberon-Src.lha - the full source of O4A Oberon-Fonts.lha - additional screen and printer fonts Dialogs.lha - advanced GUI and very nice programming example Expressions.lha - mathematical expressions within text documents Coco.lha - Compiler generator NOTE: Don't store your private files into one of the subdirectories, but rather use the top directory, or a separate one, which you can add to the assign at the end of the Oberon StartUp-Script. When started for the first time, O4A will ask for the preferred screen mode and resolution (only with asl.library >=V38). This information will be stored in the environment variable Oberon4Amiga. The command System.ChangeMode can be used to change the value at a later time. After this you can choose to use O4A at a private screen or in a window at a public screen. A private screen is the normal way. Now you should read the file Release.Notes.Text, to find out what has changed since the last release, Oberon4Amiga.Guide.Text and Welcome.Text if you use the system for the first time. If you do not know how to open an Oberon text press the Help key to read the Welcome.Text. Please note the file ReferenceCard.ps. It is a nice piece of docu. If "Oberon System V4 for Amiga" gets out of control (e.g. because of a looping command), use the KillOberon icon to terminate it. The Amiga OS has problems if a process is interrupted, while it is waiting for a message reply. To avoid problems, Ctrl-C refuses to work, when it detects a possible critical situation. System.Quit terminates the Oberon process. It is the normal way to leave "Oberon System V4 for Amiga".
