Couldn't it have been modified for Basic (there seems to be little 
difference [I/O, maybe nested loops]) easier than essentially rewriting in 
C++?

XP's lack of DOS is sc****ing up some of my legacy programs - they won't run 
in XPs emulation mode.

I remember changing the source code in a FORTRAN 0 compiler in the punch 
card era to change the output device (actually I changed the machine code in 
the compiler.
