Well, I think you are underplaying your role and work here! I mean, if I look at the (version) history… :)

Is the original source code NW's ARM compiler available, as it is for Project Oberon?

J. Yiu states for both the M0+ (RP2040) and M33 (RP2350) that the program counter (PC) is the address of the current instruction plus 4 [1][2]. The Astrobe docs say that the RP2040's PC is four bytes ahead of the current instruction, while the RP2350 is eight bytes ahead. The Arm v8-M manual says th...

Thanks for the clarification. And this strictly works with BOOLEAN CONSTs only, correct? With this facility, we could now structure modules thusly. MODULE Variant; CONST RP2040* = TRUE; RP2350* = FALSE; END Variant. MODULE M; IMPORT Variant; PROCEDURE Init*; BEGIN IF Variant.RP2040 THEN (* ... *) EL...

Thank you for your explanations and example code. Nested IFs are only ever eliminated if the IF statement that contains them is eliminated. Hence, to be sure I understand this correctly, using your example code: CONST T0 = TRUE; F1 = FALSE; PROCEDURE P4(); BEGIN IF T0 THEN IF F1 THEN Included() (* ?...

What would be the compilation and linking result of the following code, using your example (or similar, possibly nested, IF structures): IF Trace.enabled THEN Trace.Message("Init started") ELSIF OtherTrace.enabled THEN (* ... *) ELSE (* ... *) END; where 'OtherTrace' is some other tracing module, an...

It integrates Astrobe's command line tools for different MCUs into a single wo...
