As I most often am not able even to ask the right question, much lesser to understand answers, I have decided to read thoroughly Knuth's TeXbook. But on Appendix B--Control Sequences--I find reference to INITEX, no longer used in Mac Distributions. What would you suggest to a student that thinks "it is necessary to study Chemistry in order to learn how to strain a good coffee", as my problem, as I understand now is to learn how to make Formats--as stated in Knuth's TeXbook--or whatever/however I name it now? Or, should you suggest another learning path? I see no good in asking ready solutions from experts whose language I am not yet able to understand!!!!!
If you want to study TeX (as opposed to LaTeX, ConTeXt or other formats), then a book to read is TeX by Topic by Victor Eijkhout. You can buy a printed copy from Lulu. Or, if you wish to read from the screen, just call texdoc texbytopic
in a modern distribution.
After you read and understand Victor, return to The TeX book and reread it.

for your system. In particular, do read section 3.6 (starting on p. 6) on the subject of "Creating format files". – Mico Apr 12 '12 at 20:54
