Caution About MH Files and Newline Characters

[table of contents] [index]
MH commands expect their files, like the MH profile,
to end with a newline character.
(In general, you get a newline when you're using a text editor and press
RETURN.)
The vi editor will automatically terminate the last line with a
newline character.
Some other editors, including GNU Emacs, may not always put a newline at
the end.
When you edit an MH file, be careful about this.
A file that doesn't end with a newline can put MH commands like inc
into an endless loop.
If your MH commands "freeze," be sure that your MH files end with a newline.
You can use a UNIX command such
as:
% tail -1 file | od -c
000000 s h o w p r o c : m h l \n
000016
to see exactly how a file ends -- the last character should be \n.
