[tex-eplain] Creating table of contents using htstart and hlend

[Shiv Shankar Dayal]

I was going through Tex for Impatient and eplain manual. I see that it
says that I can create TOC using htstart and hlend. I am fine with
manual creation of entries. How can I refer to page no. and chapter
no? Can I declare variables like chapterone, chaptertwo and store page
no. in those to refer in this TOC?
