Hi,

The source code to C68 is available, could that be enhanced to produce reentrant code?


Hi Derek,

look in the current C68 manual. C68 can produce reentrant code, with similar options as in Lattice C. (Code size with all static variables/data restricted to 32 or 64 KByten, not sure).

The ...

@Peter:

I think you are correct. Even if the code is NOT position independent, you can write reentrant code. (In Lattice/C68 C you MUST NOT use global/static/extern variables which are volatile). But the big advantage of EJC is, that it's whole library is reentrant, so as long as your program does ...

Has anyone the Scrap Extension with functioning synchronisation between QDOS and Windows running on sQLux (or UQLX with WSL[2]).

I think I have installed all the toolkits mentioned above, but syncing the scrap between Windows and QDOS (Minerva 1.98 ...

I'm not very good in English (language). You have meant:

The problem must be in Minerva, not in sQLux (we will see, I will try it in UQLX) but in Minerva.

What I (German) have understood when I have read your message:

This is because you are using a (completely) exotic operating system.

Well ...

C68 and its Libraries do not create reentrant, ROMable code, [...]

Of course C68 creates reentrant code - if one knows how to program such code in C.

C68 has options (as Lattice C) to produce reentrant code. But there is (IMO) not even a startup object file/lib to use it and no libraries ...

You would not normally use libc in romable programs anyway. Libc is not re-entrant and also relies on global state. This is true no matter the compiler.

That's not true. At least the "standard lib" (aka Libc [#include <stdio.h>]) from EJC should produce reentrant code. If you want to test it ...

You'd have to ask Fred Toussi, who wrote Text 87 on the Atari. He probably created his own libraries.

Nope, I have had intensive contact with Fred (I wrote my "Diplom-Arbeit" with text87, the output was much better than those of other students who used WordStar, Word, ... for DOS – e.g ...

You can use Quill as an editor, but you must not save it, but export it or create a printer driver that does not translate anything and print to a file.
