15 years ago is 1998, so yes. Maybe it was even earlier?

Real mode it is, then. DPMI requires 286+ and the DOS extender that FPC 
uses is 386+. Borland Pascal 7 had a 16-bit (286+) DPMI dos extender. We 
can implement that as well, as soon as the i8086 large memory model is 
finished. The Open Watcom linker we're using already supports the 
DOS/16M extender binary format I think.
