% Some characters have a null definition supplied in TeXcoding as they cannot
% easily be represented by combinations of characters from plain TeX fonts.
% This special user-editable macro is used when a character has a null definition:
\def\missing#1{}
% preserve baseline and spacing with above and below 
\def\limit#1#2#3{\mathord{\mathop{\hbox{}#1}\limits#2{#3}}}
% loosen line break failures in TeX
\tolerance=3000
% can be modified to control minimum/maximum table column white space
\def\twtabskip{4pt plus 72pt}
% affects when section taken to next page with vertically justified documents
\def\secskip{.1\vsize}
