An alternate way may be to use array 's m column. Just don't mix m with p columns within the same tabular environment, that may have the opposite effect: if, say, you specify m for the shorter text (that ended up at the top) but p for the longer text, the shorter text gets vertically centered to the ...

Turn \aliaspagestyle{chapter}{standard} to \aliaspagestyle{chapter}{plain}

% We want all initial chapter pages on the right page not the left
\cleartoverso

That would clear to the next even numbered page, which in a twosided layout is on the left---unless you're typesetting something that's ...

I can do that simply with
\global\let\r=\r
without any iterative definition problems?

Yes. Unlike \def (or \[re]newcommand), \let creates a copy of what's on the right side of the (optional) equal sign.
Come to think of it, you might as well use

\xdef\r{\r}

which expands {\r} before it gets ...

Hello and Welcome aboard :)
Your \[ (just after the equal sign) tries to start a new (displayed) math environment, but you're already in math mode.
The last closing brace has no partner, either.
BTW: you're defining \Rho, but you're using \rho. Since (La)TeX is case-sensitive, the definition of \Rho ...

Hi Dan,
that's because the loop's, hmm, body is executed in a TeX group, so when \s is incremented, \ang and \r revert to their contents they had before the inner \foreach started (r=8, ang=0).

\@classoptionslist is still defined in the LaTeX Kernel, AFAICS. Have you considered that


\LoadClass[12pt,DIV=15]{scrartcl}


may overwrite this \@classoptionslist of yours?
I mean, you are telling to load class scrartcl with options `12pt,DIV=15', doesn't this set said \@classoptionslist ...

(though I'm not completely sure why you were so surprised that my current one does. :cry: )

I was surprised because you used the same \gdef definitions for \x, \y as in the previous code.
What I failed to realize was: said definitions no longer are within a TeX group. In other words: you may ...

Hi Dan,
I'm actually surprised your last code works :D


\gdef\x{\X}

globally defines \x to look up \X, when called--it does not expand \X.
Replace \gdef by \xdef which is short for \global\edef , then \X gets expanded.

\gdef\x{#2}

works as expected, because argument placeholders are always ...

Hi and Welcome
Perhaps it would be a good idea if you'd just post your current attempt in (La)TeX code, see also minimal working example.
That way, no one here has to start from scratch (and possibly spot what's going wrong with your code).

Hi Dan,
yes, ending a scope (or any other LaTeX environment) also ends a TeX group after which definitions made in that scope are lost.

\documentclass{article}

\def\A{foo}
\def\B{foo}
\def\C{foo}
\begin{document}
Before some group: \A, \B, \C

\def\A{bar}
