-###### This document was authored in 2019 by us before the Winter evaluation at our school. Here is the the beginners' unabridged version as documented in our assignment records, since we have a sentimental attachment with this project and to the people who contributed to it. So, the language might occasionally sound childish. Also, the documentation in this README points to the [`ZASCDS16.CPP`](https://github.com/jay-io/ZAS-16/blob/dev/git-didnt-exist-before-2005/ZASCDS16.cpp) file and not to [`zas.cpp`](https://github.com/jay-io/ZAS-16/blob/dev/zas.cpp) in the repository root.

The latter is more like an open-source version. The compiled executable was built from the open-source version of the code, and the source file in `BIN/TURBOC3/SOURCE` is the same as `zas.cpp` in the root directory.
