Handling files in GPC (with Linux)_(re)

Almost like with TP.  `Append' becomes `Extend', and with anything
older than gpc-971001 you need the `Assign' procedure from the
BPcompat package.  But then it should be the same:

    Var
      Z: String ( 1024 );

    Assign ( MyFile, 'foo.bar' );
    reset ( MyFile );
    while not eof ( MyFile ) do
      readln ( MyFile, Z );
    close ( MyFile );

That's a good thing!  :-)

The problems you are having when compiling these Units under Linux
come from the missing DPMI stuff and other DOS specifica.  Under Linux,
you have to use library functions and/or system calls instead.

Good luck,
