All commands, alphabetic order; letter Z

This page contains the description of \z@, \z@skip, \zap@space, \zap@fl@space, \zeta.

\z@ (rigid length, constant)

The \z@ command refers to a dimension, which is zero, and should not be changed. You can say \count13=\z@, because the dimension is automatically converted to an integer (with value 0). For an example, see \m@ne.

\z@skip (rubber length, constant)

The \z@skip command refers to a length, which is zero, and should not be changed.

\zap@space, \zap@fl@space (Tralics commands)

The \zap@space command removes all spaces in its argument. The end of the argument is marked by a space followed by \@empty. Tralics defines \zap@fl@space, a macro with normal syntax, that removes only initial and final spaces. In the example that follows, blue lines is what Tralics shows.

\def\includeonly#1{\edef \@partlist {\zap@space#1  \@empty}}
\def\remove@fl@space#1#2{%
\expandafter\def\expandafter #1\expandafter {\zap@fl@space{#2}}}
\def\foo{foo}
\includeonly{ bar \foo}
\remove@fl@space\gee{ \empty\space Hello World }
\show\@partlist
% \@partlist=macro: ->barfoo.
\show\gee
% \gee=macro: ->\empty \space Hello World.

\zeta (math symbol)

The \zeta command is valid only in math mode. It generates a Greek letter: <mi>ζ</mi> (Unicode U+3B6, ζ).
