I'd like an extended ResData (".ref") that not only gives the name for a module's address range, but also the procedure names (with address range) within the module. We have implemented a full application disassembler to be included in the Professional Edition in the next release. Each procedure an...

We have been working on a new disassembler for Astrobe which displays the code generated for an entire application after it has been linked. Testing has revealed that the definitions of the ISB and DSB instructions in the MCU modules for Astrobe for Cortex-M4 and Cortex-M7 have an incorrect byte ord...

The outer P (a global object) would still be hidden by the inner P (a local object) wouldn't it?

Since the Introduction of SYSTEM.COPY (equivalent to an inline version of MoveWords) an alternative implementation of Move is: PROCEDURE* Move*(fromAdr, toAdr, nBytes: INTEGER); VAR nWords, endAdr: INTEGER; byte: BYTE; BEGIN endAdr := fromAdr + nBytes; nWords := nBytes DIV 4; IF nWords > 0 THEN SYST...

Having read that 2018 discussion again, one point that stands out is the statement from the preface of the Project Oberon 2013 book: 4. Objects declared in a procedure P are not accessible within a procedure Q that is itself local to P. That is, objects must be either strictly local or global in ord...

Yes - I think you'd find it very interesting. There's nearly 20 year's worth of discussions in the archives:

Good question. Your example is currently allowed in both the Astrobe compilers and the Project Oberon compiler. However, the jury is out on this one. See the related discussion, Intermediate scopes in Oberon-07 in the ETH Oberon mailing List.

The attached zip file contains the source code of the Graphics line-drawing functions, ST7735 TFT display driver and a demo program to be used with v7.0 Astrobe for RISC5 . It displays AutoCAD Slide images of St Paul's Cathedral and the Columbia space shuttle on an 1.8" TFT Display: Slide.jpg The co...

The attached example demonstrates how to use v7.0 Astrobe for RISC5 to write applications that display text on a 1.8" 128 x 160 TFT screen using a Sitronix ST7735 Display Controller. It uses a 6x8 font stored in a file Font.res which you need to upload to your target board with the compiled source c...

v7.0 Astrobe for RISC5 includes additional source code examples, including using the button, switch and GPIO peripherals.
