Could that be the > reason? Thanks for the feedback. Yes, the user can intentionally delay submitting the password. Nevertheless, InputStr() doesn't touch entered[] and entered[0] keeps the initial value of 0X ? Still no need to check entered[0] = 0X ? ... P. -- tel: +1 604 670 0140 Bcc: peter at easthope. ca

Question about SYSTEM.BIT() in Oberon-7
by R. S. Doiel 05 Jun '21

05 Jun '21

Hello everyone, This is probably a bit of a novice question and I apologize but it has me puzzled. In the Oberon-7 language report's SYSTEM.BIT() is described as using "n" to address a specific bit. On first reading I assumed "n" zero would be the LSB and "n" thirty one would be MSB where the compiler deals with the local implementation of bit ordering. Is that the correct reading of the report? I was planning on implementing a procedure like Native Oberon's Reals.IntL() but then started having doubts about my reading of the Oberon-7 report. Have I made too simple a set of assumptions about how I should expect SYSTEM.BIT() to work under Oberon-7 implementations? All the best, Robert Doiel

Project Oberon on current 'off-the-shelf' hardware
by Chris Burrows 02 Jun '21

02 Jun '21

To help new users get started with RISC5 hardware we have made available, free of charge, a Micro SD card disk image and an FPGA bitstream file to run the Project Oberon Workstation 'out-of-the-box' on either of Digilent's latest Artix 7-100T FPGA development boards. These and the associated Pmod modules can be purchased from a number of Digilent's distributors (e.g. Mouser). This release is based on the latest official Project Oberon Workstation sources (March 2020) and RISC5 Verilog sources (September 2018) downloaded from Prof Wirth's website. The entire source code of the system, including the compiler, is included on the disk image. Go to https://www.astrobe.com/RISC5/Workstation.htm for more details including photos of the boards, and to request a copy of the system. Regards, Chris Burrows CFB Software https://www.astrobe.com

A detail which we take for granted can be a showstopper for a novice. I've revised the instructions for establishing a working copy of the A2 repository. https://en.wikibooks.org/wiki/Oberon/A2#In_a_Unix-like_System If anyone can spare a few minutes to review that, an error or shortcoming might be spotted.

The foremost motivation for creating the wikibook! Too many documents already in peril. Currently, working on the Oberon Tutorials written or organized by Andr Fischer. To whatever extent Chris and others will allow, I'm willing to incorporate further information. In fact, it's a wiki. More participation would be invaluable. Regards, ...
