If you've wondered how the FreeDOS VMATH program can do math operations on 64-bit numbers, using a 16-bit CPU, you'll want to read Jerome's article about Doing 64-bit math on a 16-bit system. With a little basic understanding of assembly, these functions could be scaled to do math on integers of any bit size.

If any of you remember Qedit, or its big brother TSE (The Semware Editor), you may be interested to know that Semware released TSE as freeware! You can download a copy at Semware's website. Note that this is the version from 1997, so it hasn’t been updated in a while. That's why the license in the readme file differs from the version displayed from inside the program. Source code is not available, but it's still great to see classic DOS software released for free so people can use it.
