[texshop] How use Carlisle's "mylatex" package with TeXShop?

[Murray Eisenberg]

(1) Does 

	% !TEX parameter = "&mylatex”

refer to making the fmt file, or typesetting runs after making the fmt file?

(2) It turns out I have to use the package mylatexformat rather than mylatex in order to successfully compile a fmt file from my source’s preamble.

In that case, do I correctly assume that I just change “&mylatex” to “&mylatexformat”?

I note that https://tex.stackexchange.com/a/377033/13492 <https://tex.stackexchange.com/a/377033/13492> gives instead the instruction to put the line

	%&foo

at the top of my source named foo during typesetting runs (after I created the .fmt).
