26.1 emacs-mac 7.2; map key to interactive lisp function (command) with an argument

[Van L]

Hello,

I am unable to have the following work.

The elisp documentation has for me the problem of tl;dr and after experimenting 
with a few paragraphs and failing I want to ask how to get this done. I wonder 
sometimes if the documentation is obtuse by design to steal time.

┌────
│ (defun x-setface-height-i (number)
│   "Face height is set to NUMBER."
│   (interactive "nInsert number: ")
│   (set-face-attribute 'default (selected-frame) :height number))
│ 
│ ;; (info "(elisp) Interactive Call")
│ (global-set-key (kbd "C-c o") (funcall-interactively x-setface-height-i 202))
│ (global-set-key (kbd "C-c O") (funcall-interactively x-setface-height-i 256))
