Fine.

Suppose I want to replace the existing DCL CLI with a new DCL CLI which
supports existing functionality but also gives DCL more modern
functionality.

[This is how bash started out BTW; it was a replacement for the limited
Unix shells of the time.]

It's easy to write a new shell on Linux (and you also have plenty of
exmaples to help you with specific concepts); where is the public
documentation which would allow me to write a new DCL CLI on VMS ?
