Oh - sorry!  Since an improved BPcompat package for DOS (DJGPP) will
be released soon, what about facing Linux instead?  Sven's BGI2GRX
(Graph) Unit runs under Linux, but we have no CRT yet ...

The same stuff as in Borland's CRT, isn't it?

Nevertheless this will remain my preferred method in BO5.  The fastest
thing you can imagine on the DOS platform.

Yes and no:  You can define a "Procedure Foo ( a, b: Integer; ... );"
with a triple dot indicating a variable number of subsequent arguments,
but I have not yet found out how to access them ...

Of course.  But a CRT Unit could use these sequences to access the
terminal in a portable way.

Don't worry.  If things develop as I hope, we will enter beta stage
soon ...
