Re: RECORD Fields with Identical Identifier
You are right - thank you for bringing it to our attention. It should be reported as a "mult def" compilation error. We have confirmed that it also occurs in the latest v9.2 version which is being released in the next day or so. Hence, for now, It will be documented in the release notes as a "Known ...

Re: Additional switches not detected on Nexys A7 board
The number of buttons, switches, LEDs etc. supported by Embedded Project Oberon is summarised in the Supported FPGA Development Boards section on the Astrobe RISC5 - Embedded Project Oberon page on the Astrobe website. Although the Nexys A7 board has 16 switches, only 8 are enabled because that is t...

Re: Can I use a USB keyboard with Embedded Project Oberon?
Embedded Project Oberon was designed to be remotely controlled with all of the user interface on the PC. I can't envisage how it might work with the keyboard being isolated from the mouse and display. The question is more appropriate to Project Oberon Workstation. This handles all of the keyboard, m...

Re: CONST Definition Question
Constant expressions are evaluated at compile time. Decimal and hexadecimal INTEGER constants are signed integers and an integer overflow in a constant expression is trapped at compile time. For example: CONST MaxInt = 07FFFFFFFH; (* PosOverflow = MaxInt + 1; Error: integer overflow *) MinInt = 0800...

Re: Copying a Procedure to RAM
I can't think of a general way to copy the executable code of a procedure to RAM that would be both useful and reliable in the current implementation of Astrobe for Cortex-M. Note that Astrobe for RISC5 supports the dynamic loading of modules (but not isolated procedures) into RAM. What is the actua...

Re: SET Parameter Problem
Thank you for your report. The problem will be fixed in v9.2. In the meantime a workaround is to assign the set to a local variable before passing it as a parameter. See the attached test program which should display the string "OK". Replacing the local variable assignment s := {k}; Check(s, k) with...

Re: Buffer Address for DMA
But non-VAR parameters? I would have expected to get a stack address, but for RECORDs and ARRAYs we get the actual address, VAR or not VAR. This is a subtle consequence of Section 10.1 of the Oberon-07 Language Report: A value parameter corresponds to an actual parameter that is an expression, and ...
