Incompatibility: Eplain 3.4 and AMSTeX 2.2?


Hello,

I'm using TL 2010 with Eplain 3.4, AMSTeX 2.2, amsppt 2.2.  It seems
they don't like to work together.  Same setup with Eplain 2.8.1,
AMSTeX 2.1, amsppt 2.1h did work.

Consider following input file:

\input amstex
\documentstyle{amsppt}
\input amssym.def

\input eplain
\input miniltx
\beginpackages
\usepackage{graphicx}
\endpackages

Test

\eqdefn{eq:al}
$$\align
a &= b \tag\eqsubdef{eq:a}\\
c &= d \tag\eqsubdef{eq:b}
\endalign$$

\bye

Any idea how to solve following two errors?  Thanks in advance.

Hello Dan,

Thanks for the fix!

Using the natural order, it seems there's another problem:

Without loading amstex/amsppt, following fragment produces the expected 
output

\def\text#1{\hbox{#1}}

\frac{1}/2

$\text{\frac{3}/4}$

${\text{\frac{5}/6}\over 1}$

\bye

Replacing \def\text... by

\input amstex
\documentstyle{amsppt}
\input amssym.def

results in

! Missing $ inserted.
