(AmS-TeX's alternatives \oldnos and \Cal can +%% also still be used, though it would be pretty confusing to use +%% \oldstyle and \oldnos together, or \cal and \Cal together, since +%% the plain constructions work like font changes, while the +%% AmS-TeX constructions work like control sequences with an argument.) + +%% The \mit command, used for things like \mit\Gamma, is a little +%% different, since AmS-TeX doesn't regard upper-case Greek letters +%% as ``variables'' that can change fonts. However, if you type +%% +%% \variableGreek +%% +%% then \mit can be used in this way. + +%% Typing +%% +%% \plaincases +%% +%% makes \cases have the plain syntax, rather than the AmS-TeX +%% syntax. Similarly, +%% +%% \plainmatrix +%% +%% makes \matrix have the plain syntax, rather than the AmS-TeX +%% syntax. Finally, +%% +%% \plainfonts +%% +%% allows \rm, etc, to be used in math formulas, whereas AmS-TeX +%% only allows \rm within \text within a math formula (but remember +%% that $\rm two words$ will not give any spaces between the +%% letters, while AmS-TeX's $\text{\rm two words}$ will). + +%% \variableGreek, \plaincases, \plainmatrix, and \plainfonts +%% can each be used within a group, if part of the paper uses +%% plain conventions, while part uses AmS-TeX conventions. + +\catcode`\@=11 +\def\oldstyle{\fam\@ne\the\textfont\@ne} +\def\cal{\fam\tw@} +{\catcode`\"=12 +\gdef\variableGreek{\mathchardef\Gamma="7000 + \mathchardef\Delta="7001 + \mathchardef\Theta="7002 + \mathchardef\Lambda="7003 + \mathchardef\Xi="7004 + \mathchardef\Pi="7005 + \mathchardef\Sigma="7006 + \mathchardef\Upsilon="7007 + \mathchardef\Phi="7008 + \mathchardef\Psi="7009 + \mathchardef\Omega="700A + \def\mit{\fam\@ne}} +} +\def\plaincases{% + \def\cases##1{\left\{\,\vcenter{\normalbaselines\m@th + \ialign{$####\hfil$&\quad####\hfil\crcr##1\crcr}}\right.}} +\def\plainmatrix{% + \def\matrix##1{\null\,\vcenter{\normalbaselines\m@th + \ialign{\hfil$####$\hfil&&\quad\hfil$####$\hfil\crcr + \mathstrut\crcr\noalign{\kern-\baselineskip}% + ##1\crcr\mathstrut\crcr\noalign{\kern-\baselineskip}}}\,}% + \def\pmatrix##1{\left(\matrix{##1}\right)}} +\def\plainfonts{\def\rm{\fam\z@\tenrm}\def\it{\fam\itfam\tenit}% + \def\sl{\fam\slfam\tensl}\def\bf{\fam\bffam\tenbf}\def\smc{\tensmc}% + \def\textonlyfont@##1##2{\def##1{\fam\csname\exstring@##1fam\endcsname##2}}} +\catcode`\@=\active
