I don't see how you could use procedure types to do this. All you need to do is something like: CONST InitSequenceSize = ???; TYPE ConstVal = INTEGER; (* You need v5.3 Astrobe to use type aliases otherwise just use INTEGER instead of ConstVal *) InitSequence = ARRAY InitSequenceSize OF ConstVal; VAR...

I need more details, preferably with a number of examples, of what you are trying to do, rather than an example of how you are trying to do it, to be able to tell if you are on the right track or if there is a better way. e.g. do you have a number of strings that you want to associate numbers with? ...

So essentially, RISC0 as a 'soft processor' where you have implemented a way to upload executables to a ram section, would you say? Is it a traditional 'soft processor' like the Zpuino or MicroBlaze? Yes - except that Project Oberon is implemented on the more advanced RISC5 'soft processor' rather ...

... your goal is to be able to create "programs" which are based on the current "targets" available in Astrobe to "flash" to the ProjectOberon OS on the FPGA? Or does it create the whole flashable .bin file? The initial implementation will only need a minimal version of the Project Oberon OS e.g. t...

Yes - work is progressing well. We have ported the FPGA RISC5 Oberon compiler to Windows and integrated it into an experimental version of Astrobe to use as a cross-compiler. We were able to successfully execute a simple RISC5 Oberon application it generated for the first time today after we uploade...

Storage is a special case and you do have to be careful in its use - I'll make a note to point this out in the documentation. Note that you only need to import Storage if you have modified it in any way. The compiler automatically imports MAU and calls its functions when you use NEW and DISPOSE. If ...

Each version of Astrobe has its own registry settings to remember the last used folder, configuration file etc. so it shouldn't matter how you setup your folders. All you should have to do is replace the string '%astrobe%' in your configuration files ( Library Pathnames ) with the actual pathname e....

Niklaus Wirth's article Oberon System Implemented on a Low-Cost FPGA Board including an overview of Lola, his Oberon-like hardware description language (HDL) is featured in this month's issue of Xilinx's Xcell Journal (Issue 91). You can download a pdf copy . Watch out for Astrobe developments relat...

Code: Select all

CaseLabelList = LabelRange {"," LabelRange}.
label = integer | string | qualident.

Great news - that was a quick response! We have now implemented support for qualified identifiers as CASE statement labels in the Astrobe compiler.
