Hi Ralf,
the tests I did showed that FreePascal is perfectly capable of producing
reasonably small binaries fitting the small memory model, if you do not
require the full language feature set (stay away from ObjFpc / Delphi
modes). SysUtils and exception handling pulls in a significant amount

Hello,
Could you please post the exact message you got from the compiler?
I got mysefl problems with such convertions trying to compile FD-KEYB with
FPC, but although I posted for help in the forums, I didn't get anything
really useful and finally gave up.
But I am curious if you get the same err
Hello Aitor,
> Could you please post the exact message you got from the compiler?
For something like this "FarPointer(@Buffer)" I get the following error
message:
"Error: Illegal type conversion: "Pointer" to "FarPointer""
My opinion is that this should be supported by the compiler, because
Btw, when compiling in large memory model via
fpc -Wmlarge
the pointer errors when compiling keyb are gone. There are some 20
remaining compile errors. Perhaps these can be solved.

As far as I know the earlier Turbo-Pascal compilers (I think 5.5 and
earlier) have been freeware'd years ago. They can natively compile
16bit code on Freedos and might be worth a try. You can find even
ancient versions of TP, like 3.0 on winworldpc, and I actually quite
like to go down memory lane
Hello Hippo,
thanks for the hint. I have a copy of Borland Pascal 7 inherited from my
father. In fact I think I have learned programming with it when I was a kid, or
with a previous version. Fascinating piece of software. But I prefer to build
open tools with open tools :-)

Hello Rugxulo,
Yes, Watcom C supports 64-bit integer arithmetic, in contrast to Turbo C 3.1,
which to my knowledge does not, but silently interprets „long long x“ as „long
x“, yi

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 inst

Hello there!
Sorry for being late on the topic.
The following link directs to the forum item that I opened when trying to
re-compile FD-KEYB under FPC.
Basically, KEYB needs to use different procedures to store a key in the
buffer, depending on the parameters and system configuration. The problem
Perhaps you may first try get it running with the large memory model,
and if this runs, try to optimize it for a smaller memory model? The
following least compiles for me, with A BUNCH of warnings, and the
binary is 68k in size, comparing to 11k in the bin folder (did you UPX
compress it or is
