I decided to give the compiler a work out by converting an old BASIC game listing - BOMBER from ACU issue 2. Translating BASIC to structured code is ‘interesting’.
Sound and user defined characters would require records and array literals to do without major bodges. Everything else converted fine.
A few bugs did show up. Nothing maker, although they should have been caught in self tests.

Last up is value parameters for 'pointered types' (those which are passed via pointers rather than in registers). The function needs to be able to modify the data without affecting the original value. That means a 'hidden' copy of the data (the array) into the function's static variable space. No data need be passed in registers - the function can use the static address of the variable/data.

The caller has to copy the data into the correct stack location. The challenge is that the caller is not in the function's stack frame, so it's need to calculate where data must go as an offset from the current SP. And that offset will depend on how many parameters are still to be pushed on the stack.
The code here isn't actually very complex, but it's a mind freak.

🔥 Top post I love that the CPC was probably the best documented home computer, but reading references manuals in PDF form is tedious so I've converted the Firmware Manual (Soft968) into a hyperlinked website. The project is based off the pre-existing PDF edition (With all credit to the ori… ★ 27

Here's screenshot and a section of the listing. As mention there are no user defined characters so just random data. I gave user friendly names for the functions that do firmware calls and they work really nicely (Quiche can 'import' assem…

That wasn't too difficult to get working. The atomic unit of expressions is the TExprSlug, either for the result of an expression, sub-expression or function.
