DOS is still used for critical embedded applications, such as
process control, where Windows is simply too unreliable, and Linux
may be overkill.

DOS also gives the fastest possible performance, since you own the
cpu and don't have to give up cpu cycles for multitasking. That's
the reason I mentioned it - the response while sifting through a
megabyte of data was practically instantaneous from the keyboard,
but it would be a bit slower in Windows.

However, that was on a 450MHz AMD K6 cpu. I would expect higher
performance on a more modern 2GHz+ cpu for home lab applications.

Since the code is in Borland Pascal, it would be very
straightforward to transfer it to Free Pascal and run it in Windows,
or even to Linux running on an X86 machine.

The main point is sifting through a megabyte of data can be very
fast if you have taken a bit of care to optimize the code.
