The free compiler reports itself as version 5.5 and is the set of C++
Builder 5 command line tools.  It creates 32 bit programs for the current
versions of Windows.

The code you show is 16 bit code for DOS.  C++ Builder does not create 16
bit code and does not use far pointers.  The current versions of Windows are
now 32 bit and do not support direct access of video memory.

In a console mode (text mode) program you can write to the screen with
functions such as putchar, printf, puts, cputs, putch or cprintf, the same
functions as are used in a 16 bit DOS program.  If you have a need to place
the data in a block of memory on the screen you could use puttext and to
read it back use gettext.
