Re: [Freedos-devel] New FreeDOS Edlin 2.23 is out on Sourceforge!
Thanks! I always love a new Edlin release. :-) I've mirrored it on the FreeDOS Files Archive at Ibiblio. Here's the link: https://ibiblio.org/pub/micro/pc-stuff/freedos/files/dos/edlin/2.23/ For anyone interested, the video Gregory mentioned is here: https://www.youtube.com/watch?v=yapAepxbaT4 The compile warning is at 2:47 (yes, this is confirmed fixed in Edlin 2.23 using OpenWatcom C) FYI that if you compile this on FreeDOS, Edlin 2.23 will actually advertise itself as "2.22". To fix, you'll need to edit config-h.bc or config-h.ow (depending on your compiler .. I used config-h.ow to compile with OpenWatcom C) and change all occurrences of "2.22" to "2.23" (3 occurrences in each file).

[Freedos-devel] New FreeDOS Edlin 2.23 is out on Sourceforge!
When Jim compiled Edlin 2.22 for the video, I noticed that the OpenWatcom compiler emitted a warning. Of course, this caused a disturbance in the Force. The new version 2.23 cleans up that warning, and therefore FreeDOS Edlin can now be thrown into the gladiatorial arena and slay the software demons called Fear, Doubt, Uncertainty, and Proprietary.

Re: [Freedos-devel] libm-0.6 and libmpi-0.2
Hi everyone! For anyone who needs more info: libmpi is a Multiple Precision Integer library, and libm is a C math library. Both are public domain. You can find both on the FreeDOS Files Archive at Ibiblio, under /files/devel/libs/libm and /files/devel/libs/libmpi. Thanks Gregory! Here are the direct links: https://ibiblio.org/pub/micro/pc-stuff/freedos/files/devel/libs/libm/0.6/ https://ibiblio.org/pub/micro/pc-stuff/freedos/files/devel/libs/libmpi/0.2/ On Sun, Nov 12, 2023 at 9:33 AM Gregory Pietsch via Freedos-devel wrote: > > In a world where mathematicians are the lowest of the low, I have sent Jim > the latest versions of these low-level libraries.

[Freedos-devel] libm-0.6 and libmpi-0.2
In a world where mathematicians are the lowest of the low, I have sent Jim the latest versions of these low-level libraries. These versions contain mostly bug fixes.

Re: [Freedos-devel] FreePascal near to far pointer conversion
On 12.11.2023 02:44, Rugxulo via Freedos-devel wrote: FarAddr internal function Thanks, that brings me further :-) I also changed my coding style from a more C oriented style to a more Pascal like. Unlike in C, one does not have to pass around (explicit) pointers that often. For example instead of doing procedure F(buffer : FarPointer); I now do: procedure F(var buffer); begin ... ... FarAddr(buffer) ... ... But I still have not found an elegant solution yet to do a widening conversion of an untyped pointer from near to far. Should be rarely needed though. For a typed pointer FarAddr(thing^) does the trick. Bernd ___ Freedos-devel mailing list Freedos-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-devel
