If I understand correctly, the "continue=3Dyes" key prevents a new page generated by a lower-level structure, e.g., section, following a higher-level structure, e.g., chapter.

Then why the checking is so complex in strc-sec.mkiv:

Seems fine.



PS: irrelevant to my problem, but I just wish ConTeXt to be perfect. So:
1, line 1060, file strc-sec.mkiv:
\global\setfalse\c_strc_rendering_continue
shouldn't this line be "\global\setfalse\c_strc_rendering_continuous"?
2, a lot of \.._strc_sectioniong_... macros in strc-sec.mkiv. I think changing the "sectioniong" to "sectioning" may prevent potential typos.

Dear Hans and Wolfgang,

The following code generates a pdf that I cannot understand.

1. Although "placehead" is set to "no," the \part macro still makes an em=
pty line.
2. The first \chapter does not open a new page, but if we switch the firs=
t \title
    and the first \chapter, the result seems to be all right.

Is there a simple fix?

Thanks in advance.
