Chapter 27 of the TeXbook recommends only to do global assignments 
with macros or registers or internal parameters that /always/ get global 
assignments. E.g., \@gtempa is used as a macro for /global/ temporary 
assignments, while \@tempa etc. should be changed /locally/ only. As 
\count@, \dimen@, ... get local assignments, they should not be changed 
globally accordingly. \dimen at i is allocated for /global/ changes in plain/LaTeX 
(but latex.ltx doesn't use it).
