In plain.tex and consequently in lplain.tex there are \mathcode
assignments for control-a (ASCII 1) and the like. A while ago I
removed all these from lplain.tex (without someone noticing it, it
seems). Is there any reason why these should remain?
Example:
{\catcode`\^^Z=\active \gdef^^Z{\not=}} % ^^Z is like \ne in math
Another issue are active math characters. Currently there are:
\mathcode`\ ="8000 % \space
\mathcode`\'="8000 % ^\prime
\mathcode`\_="8000 % \_
I can see the reason for prime, but why the other two?
