Yes, but currently i'm a bit lost here. Since that combination
currently does not support "smart linking", i guess i'll stick to vasm
for now. There are other parts that should be improved, and seem more
important to me (like ARGV support, completing the GEMDOS/BIOS/XBIOS
interface etc)
Currently i'm trying to figure out whats wrong with readln() (used eg.
when getting the help screen). On both TOS anfd MiNT, i have to press
"return" three times. But can't find where readln(textfile) (without
any extra arguments) is implemented. All i can find is some
declaration in inc/system.fpd, and the procedure fpc_readln_end in
inc/text.inc. Is that actually the function which is called? And how
does that magic work? I expect there some problem with expecting CR/LF
also when reading from console (although the win32 platform does not
seem to suffer from this)
Read(Ln) and Write(Ln) are compiler intrinsics as such you won't find
them as-is in the sources. To find out what code is generated for it
it's best to check the generated assembly code. In case of ReadLn it's
indeed fpc_readln_end that does the main job.

Sven
