[net.text] fixed-pitch spacing in ordinary troff

reid@glacier.ARPA (Brian Reid) (11/30/85)

Can anybody tell me the magic troff incantation for jimmying a font
so that its characters come out in a fixed-pitch spacing? I'd like
to be able to print netnews ".signature" files in troff, and have
all of the cute graphics come out. I know about the ".cs" command,
but I don't know what arguments to give it and I don't know how
to un-do its effect when I am done with the fixed-width stuff.

The format is
		.cs F [N [Msize]]

	F - Font
	N - Width in 1/36 em units; Turn off if omitted.
	M - Width of an em (optional)

Example:
	.cs R 36   (or ".cs 1 36" for font position 1 if you prefer)

will change to constant pitch with each char a width of your "em",
and,
	.cs R      ( or ".cs 1")
will revert back to normal.

Or, you can also select a constant width font. For example:

	.ft CW		- Constant Width
	.ft P		- back to previous font

I'd be interested in hearing about this too.  We supposedly have fixed width
fonts but they aren't TRULY fixed width.  We have some applications where the
characters must align all the way down a page.  I've looked at the width tables
for these fonts and the characters are all set to the same width.  It is some
anomally or misuse of troff that is causing the characters to not line up.

Well, let's see. One possible way of getting bad results would be if you
followed the halfway correct answer that elan!kg (Ken Greer) posted earlier
in this newsgroup. Ken's solution is identical to the one that I had come up
with and which did not work, thereby causing me to ask for help. Matt Bishop
of RIACS and Bernie Cosell of BBN both sent me correct solutions (correct ==
they work in my application). Since both Matt and Bernie read net.text, I'll
leave it to one of them to post their explanation. Matt, yours was an
in-depth explanation of the problem, and Bernie, yours was a macro package
that works, so perhaps both of you should do it.

The problem with Greer's solution is that it does not work in traps and
diversions. To my jaundiced eye this is primarily a condemnation of the
whole idea of traps and diversions, but that's another story.
