August 12, 2020 Dear Jim, having used FreeDOS extensively for years I came accross the nice video meeting in summer. As I emntioned at that occasion. I have ported quite a few unix utilities for FreeDOS. I am enclosing as an example the whereis version (for 32bit and 16 bit gcc). It can be compiled for 32 bit with djgpp: gcc -O4 -fexpensive-optimizations -c whereis.c gcc -o whereis whereis.o It can be compiled for 16 bit with gcc-ia16 : gcc -O4 "-mcmodel=medium" -fexpensive-optimizations -c whereis.c gcc "-mcmodel=medium" -o whereis.exe whereis.o Best wishes Burkhard Meißner
