Re: Register R13
Refer to Section 8.1 Layout and run-time organization of the Project Oberon (2013) Documentation: R13 base address for variables in the current module SB (static base) If you then look at the RISC5 compiler modification history you will see the following entry for 2018: 20180720 - Update compiler: O...

Re: SYSTEM.LDREG
That particular section of code is taken 'as is' from the Project Oberon source code. As far as I am aware LDREG is an 'undocumented feature' in the RISC5 compiler - I have only seen it mentioned without explanation in some example code. Hence, you should make no assumptions about what it should or ...

Lola2 Compiler Source Code
The hardware description language (HDL) Lola (Logic Language) was designed by Niklaus Wirth in 1990 as an effort to present a simple and effective textual description of digital circuits. Other, similar but more complex, HDLs that you may have heard of are VHDL and Verilog . The use of the Lola2 com...

RISC5 Oberon Compiler Source Code
CPIde now includes the full source code for an Oberon for FPGA RISC5 command-line compiler as example code. These are the same source code modules used for the Oberon compiler in Astrobe for FPGA RISC5 . Consequently, the source code, symbol files and code files it uses and generates are 100% compa...

Re: Spurious Imports
I have checked and as far as I can see the Astrobe compiler more or less works like the Project Oberon compiler as far as indirect imports go. As an example, if module M1 imports Texts and module M1 exports an item that references Texts then a module that imports M1 will indirectly import Texts as w...

Re: Spurious Imports
The v8.0 Astrobe compiler includes some modifications to the way symbol files are handled to as mentioned in the What's New notes: The items in an IMPORT list may now be included in any order. The sequence is not affected by dependencies or indirect imports. I'm on leave right now - I'll check somet...

Re: Spurious Imports
Search for the word ''índirect'' in the Project Oberon book and you will find references to indirect module imports which should help in understanding when they occur and why they are needed.

Main Menu for a Windows App
The attached example included with CPIde shows how to create a basic Windows App with a main menu. When you select a menu item the menu caption is displayed on the StatusBar. The code includes a function which uses the .NET StringBuilder functions to efficiently strip non-alphabetic characters from ...

Debugging GPCP using Visual Studio
John Gough (the author of the Gardens Point family of compilers, including GPCP) wrote an article to address this issue: Back in the early days of Visual Studio.NET the IDE shipped with a program called DbgCLR, which was found in a GuiDebug directory in the VS distribution. Since VS-2008, this progr...
