Get a list of used AutoLISP commands

[Nikon]

Good day to everyone.
Is it possible to display a list of AutoLISP commands before closing and saving the dwg file?
For example, in notepad or text in dwg.

I assume you're referring to commands defined in Lisp code.

One way to do this is to call ATOMS-FAMILY, save its contents in a variable, call ATOMS-FAMILY again when the drawing is about to be closed, compare the difference, and filter out symbols that don't begin with "c:"

 

But why do you need to do this?

Perhaps this old program?

LISPLogV1-0.lsp is a very convenient program. Thanks @Lee Mac.
Is it possible to get a list of lisp commands in the drawing? That is, when saving a drawing, a request appears: 
"Save a list of lisp commands?" and the text with the commands is inserted into the drawing?

I often have to go back to old drawings. I have over 300 lisp programs. 
I would like the drawing to have a list of programs used to continue working, 
but over time it is not always possible to remember the name of the desired program.
