How to change the page number from bottom center to top left?

Question

This .sty file is provided to me and the page number is currently at the bottom center (i.e. footer). I want to change it to the top left (i.e. header), which part is referring to the page number location? Or how can I narrow down my search and find out the corresponding region of the code? Thanks for your help in advance.

Answer 1

Region of code you need are the @oddhead and @oddfoot macros.

This style seems not to redefine them, so they are "standard". If you require only page numbering in the header, you can use \pagestyle{empty} and define @oddhead with \def as

\makeatletter    
\def\@oddhead{\arabic{page}\hss}
\def\@oddfoot{}
...
\makeatother
