documentation for this version of T\h-0.1667m\v0.20vE\v-0.20v\h-0.125mX can be found in the info file
Web2C: A TeX implementation.
The A\h-0.1667m\v0.20vM\v-0.20v\h-0.125mST\h-0.1667m\v0.20vE\v-0.20v\h-0.125mX language is described in the book
The Joy of TEX. A\h-0.1667m\v0.20vM\v-0.20v\h-0.125mST\h-0.1667m\v0.20vE\v-0.20v\h-0.125mX is a T\h-0.1667m\v0.20vE\v-0.20v\h-0.125mX macro package, not a modification to the T\h-0.1667m\v0.20vE\v-0.20v\h-0.125mX source
program, so all the capabilities described in
The A\h-0.1667m\v0.20vM\v-0.20v\h-0.125mST\h-0.1667m\v0.20vE\v-0.20v\h-0.125mX macros encourage writers to think about the content of their
documents, rather than the form. The ideal, not always realized, is to
have no formatting commands (like switch to italic or skip 2
picas) in the document at all; instead, everything is done
by specific markup instructions: emphasize, start a section.
For authors more familiar with L\h-0.36m\v-0.15vA\h-0.15m\v0.15vT\h-0.1667m\v0.20vE\v-0.20v\h-0.125mX, an AMS-supported package called
amsmath.sty is available, among others.
