When DEC introduced TPU/EVE, I raised my arms to the heavens in joy at
finally being liberated from the suffering that was EDT. (Hate EDT. Hate,
hate, hate.)

Then I left it behind with VMS ... and a few decades later, finally found
the time to get to grips with Emacs.

In Emacs/ELisp, there is the distinction between a “function” (what TPU
would call a “procedure”, I guess) and a “command”. A “function” only
becomes a “command” when you insert the “(interactive ...)” directive near
its start. This is a declarative construct that supplies the information
Emacs uses to obtain the right arguments for the function automatically,
including prompting the user as necessary, so your code doesn’t have to.
