+Here the main document starts. It should be in double columns until
+further notice. It's all one paragraph. I am going to use Wuthering
+Heights, as usual. With that concluding word, the whole assembly,
+exalting their pilgrim's staves, rushed round me in a body; and I,
+having no weapon to raise in self-defence, commenced grappling with
+Joseph, my nearest and most ferocious assailant, for his. In the
+confluence of the multitude several clubs crossed; blows aimed at me
+fell on other sconces. Presently the whole chapel resounded with
+rappings and counter-rappings. Every man's hand was against his
+neighbour; and Branderham, unwilling to remain idle, pour\-ed forth his
+zeal in a shower of loud taps on the boards of the pulpit, which
+responded so smartly that at last, to my unspeakable relief, they woke
+me. And what was it that had suggested the tremendous tumult? What had
+played Jabes's part in the row? Merely the branch of a fir-tree that
+touched my lattice, as the blast wailed by, and rattled its dry cones
+against the panes! I listened doubtingly an instant, detected the
+disturber, then turned and dozed, and dreamt again---if possible, still
+more disagreeably than before. This time I remembered I was lying in
+the oak closet, and I heard distinctly the gusty wind and the driving of
+the snow. I heard also the fir-bough repeat its teasing sound, and
+ascribed it to the right cause. But it annoyed me so much that I
+resolved to silence it, if possible; and I thought I rose and
+endeavoured to unhasp the casement. The hook was soldered into the
+staple---a circumstance observed by me when awake, but forgotten. ``I
+must stop it, nevertheless!'' I muttered, knocking my knuckles through
+the glass, and stretching an arm out to seize the importunate branch;
+instead of which, my fingers closed on the fingers of a little, icecold
+hand!
+
+The intense horror of nightmare came over me. I tried to draw
+back my arm, but the hand clung to it, and a most melancholy voice
+sobbed, ``Let me in---let me in!'' ``Who are you?'' I asked, struggling,
+meanwhile, to disengage myself. ``Catherine Linton,'' it replied
+shiveringly. (Why did I think of Linton? I had read Earnshaw twenty
+times for Linton.) ``I'm come home. I'd lost my way on the moor.'' As
+it spoke, I discerned, obscurely, a child's face looking through the
+window. Terror made me cruel; and finding it useless to attempt shaking
+the creature off, I pulled its wrist on to the broken pane, and rubbed
+it to and fro till the blood ran down and soaked the bedclothes. Still
+it wailed, ``Let me in!'' and maintained its tenacious gripe, almost
+maddening me with fear. ``How can I?'' I said at length. ``Let me go,
+if you want me to let you in!''
+

+Now we should be typesetting in a single column, i.e., normally. The
+fingers relaxed; I snatched mine through the hole, hurriedly piled the
+books up in a pyramid against it, and stopped my ears to exclude the
+lamentable prayer. I seemed to keep them closed above a quarter of an
+hour; yet the instant I listened again, there was the doleful cry
+moaning on! ``Begone!'' I shouted; ``I'll never let you in---not if you
+beg for twenty years.'' ``It is twenty years,'' mourned the
+voice---``twenty years. I've been a waif for twenty years!'' Thereat
+began a feeble scratching outside, and the pile of books moved as if
+thrust forward. I tried to jump up, but could not stir a limb, and so
+yelled aloud in a frenzy of fright. To my confusion, I discovered the
+yell was not ideal. Hasty footsteps approached my chamber door; somebody
+pushed it open with a vigorous hand, and a light glimmered through the
+squares at the top of the bed. I sat shuddering yet, and wiping the
+perspiration from my forehead. The intruder appeared to hesitate, and
+muttered to himself. At last he said in a half-whisper, plainly not
+expecting an answer, ``Is any one here?'' I considered it best to
+confess my presence, for I knew Heathcliff's accents, and feared he
+might search further if I kept quiet. With this intention I turned and
+opened the panels. I shall not soon forget the effect my action
+produced. Heathcliff stood near the entrance, in his shirt and
+trousers, with a candle dripping over his fingers, and his face as white
+as the wall behind him. The first creak of the oak startled him like an
+electric shock. The light leaped from his hold to a distance of some
+feet, and his agitation was so extreme that he could hardly pick it up.
+``It is only your guest, sir,'' I called out, desirous to spare him the
+humiliation of exposing his cowardice further. ``I had the misfortune
+to scream in my sleep, owing to a frightful nightmare. I'm sorry I
+disturbed you.''

+Humulene monoepoxides exist in hop essential oil and were suggested
+as one of the important contributors of hop flavor to fermented
+malt beverages [1-3]. However, it is more possible that the ``noble
+hop'' aroma compounds are produced from certain hop components
+during the brewing process, because the ``noble hop'' aroma is
+distinct from ``dry hop'' aroma. The aging of hops, during which the
+amount of oxidation products of humulene increases [4], is also
+necessary to develop the ``noble hop'' aroma. One approach to find
+out the flavor compounds and their origin is to examine the brewing
+products of the oxygenated sesquiterpenes. The reactions of the
+brewing process can be simplified to hydrolyzation and fermentation
+as the first step. We have been investigated the hydrolysis of
+humulene monoepoxides.
+\singlecolumn
+To simulate the hydrolyzation effect in the ``late hop'' brewing
+process, humulene monoepoxides were boiled in water at
+pH\thinspace 4 for 10 minutes. After boiling, a large amount of
+the epoxides remain unreacted. When the solution was kept at
+ambient temperature for several weeks, humulene epoxides were
+then almost completely hydrolyzed. To accelerate the hydrolysis
+process, humulene epoxides were suspended in a aqueous solution
+buffered at pH\thinspace 4 and boiled for three hours under
+reflux. All three humulene monoepoxides produced a complex
+mixture after the reaction (Figure 1). The hydrolysis products
+can be easily separated into two groups by extraction with
+pentane and dichloro\-me\-thane subsequently. The pentane
+extracts are less polar, more volatile and smell stron\-ger than
+the dichloro\-methane extracts. Sensory evaluation of the
+hydrolysis products of humulene epoxide II and III by sniffing
+gas chromatography effluent indicates that some of the compounds
+have the flavor notes which are close to the ``noble hop'' aroma
+character described as ``spicy, citrus, floral'' (Table 1).

+\line{did we mess up plain's line in equation \eqref{line1}?\hfil}
+
+\bye
+
+The first equation:
+$$x + y = 1 \eqdef{first}$$
+
+In equation \eqref{first}, we said that $x+y=1$.
+Now, in equation \eqref{second}, we say that $a+b=2$.
+
+$$a + b = 2 \eqdef{second}$$
+
+The next equation is unlabeled in the output, but we can still refer to
+it.
+$$c + d = 3 \eqdefn{*}$$
+
+And here's an equation whose text references another equation, namely,
+\eqref{first}:
+$$c=3\eqdef[\eqrefn{first}*]{first-star}$$
+And a reference to it: \eqref{first-star}.
+
+Here is the first of a group of equations: \eqdefn{group}
+$$a = 1\eqsubdef{group-1}$$
+and the invisible second, then the third of the group \eqsubdefn{group-invis}:
+$$b = 2\eqsubdef{group-2}$$
+We refer to the group as \eqref{group}, to the first as
+\eqref{group-1}, the third as \eqref{group-2}, and the invisible second
+as \eqref{group-invis}.
+
+Here's an equation labeled strangely:
+$$a=1\eqdef[\rm strange*]{foo}$$
+And let's refer to \eqref{foo}.
+
+Let's do subequations off that:
+$$b=2\eqsubdef{foo-1}$$
+And refer to it: \eqref{foo-1}.
+
+% We can't use \count255, since #1 might involve contortions which
+% trample it.
+\newcount\subrefcount
+\def\eqsubreftext#1#2{%
+ \subrefcount = #2

+
+Let's try another group, with a different labelling scheme. Here is the
+first of this group2: \eqdefn{group2}
+$$a = 1\eqsubdef{group2-1}$$
+and the second of the group2 \eqsubdefn{group2-invis}:
+$$b = 2\eqsubdef{group2-2}$$
+We refer to the group2 as \eqref{group2}, to the first as
+\eqref{group2-1}, the third as \eqref{group2-2}, and the invisible second
+as \eqref{group2-invis}.
+
+Here is one done with displaylines:
+% The \hfill's and \llap make the equation numbers come out in the right
+% place if we are not doing \leftdisplays. (See the TeXbook, p.194.)
+%$$\displaylines{

+%}$$
+$$\displaylines{
+ x=1\eqdef{displayline-1}\cr
+ y=2\eqdef{displayline-2}\cr
+}$$
+
+Let's refer to each of the equations in the displaylines:
+\eqref{displayline-1}, \eqref{displayline-2}.
+
+And one with eqalignno:
+$$
+\eqalignno{
+ a+b&=c&\eqdef{eqalign-1}\cr
+ d+e&=f&\eqdef{eqalign-2}\cr
+}
+$$
+
+And one with leqalignno, and indented more:
+{\leftdisplayindent = 1in
+$$\leqalignno{
+ a+b &=c&\eqdef{leqalign-1}\cr
+ dt+eg&=f&\eqdef{leqalign-2}\cr
+}$$
+}
+
+And now let's refer to those: \eqref{eqalign-1}, \eqref{eqalign-2},
+\eqref{leqalign-1}, \eqref{leqalign-2}.
+
+
+
+\def\eqprint#1{[\rm A.#1]}
+
+From now on, all equation labels should be in brackets and preceded
+by `A.'. In \eqref{*}, we said that $c+d=3$. And in equation
+\eqref{undefined}, we say that $1+1=2$.
+
+\eqdefn{*x}
+\eqdefn{*y}
+
+We defined equation \eqref{*y}, although we didn't give an equation for
+it.
+This is a forward reference to equation \eqref{forward}.
+
+$$e + f = 4 \eqdef{forward}$$
+
+That equation above defines \eqref{forward}.
+
+
+\newcount\sectionnum \sectionnum = 1
+\def\eqconstruct#1{\the\sectionnum.#1}
+
+And now equation numbers should have a section number (which we start at
+one) preceding them.
+
+$$a+b=1 \eqdef{s-ab}$$
+
+That equation is \eqref{s-ab}. The one we'll define in the next section
+is \eqref{s-cd}.
+
+
+\advance\sectionnum by 1
+The equation in the previous section was \eqref{s-ab}. Let's define one
+in this section:
+
+$$c+d=3 \eqdef{s-cd}$$
+
+And refer to it: \eqref{s-cd}.

+%Subject: Re: eplain

+%
+%Karl--
+%
+%Here are my multi-column macros and a rewrite of the double columns section
+%of eplain.texinfo. I included a \quadcolumns because this seems potentially
+%useful on landscape pages.
+%
+%I ran into a couple of problems/bugs/features of the original macros that I
+%think I've fixed.
+%
+%First, if I started double columns and then returned to single column before
+%the output routine was invoked, but there was too much text in the columns to
+%fit on the current page, then all of the text was put on the next page, leaving
+%lots of blank space on the first page. I think I've fixed this by changing how
+%\vsize is defined.
+%
+%Next, unless I'm doing something screwy, it looks to me like eplain goofs up on
+%footnotes and topinserts issued in multicolumn mode. I think I've got things
+%changed around so they work.
+%
+%I also discovered that the "\vskip\interfootnoteskip" in the vfootnote macro
+%will produce a parskip even if the interfootnoteskip is 0---was this
+%intentional? If not, perhaps you'd like to add \parskip=0pt to vfootnote.
+%(I have already added it to the modified vfootnote in the columns macro).

+@cindex multiple column output
+ Eplain provides for double, triple and quadruple
+column output: you just say
+@code{\doublecolumns},
+@findex doublecolumns
+@code{\triplecolumns}
+@findex triplecolumns
+or @code{\quadcolumns}
+@findex quadcolumns
+and from that point on, the manuscript will be
+set in columns. If you want to go back to one column, say
+@code{\singlecolumn}.
+@findex singlecolumn
+
+ The columns macros insert the value of the glue parameter
+@code{\abovecolumnskip}
+@findex abovecolumnskip
+before the multi-column text, and the value of the glue parameter
+@code{\belowcolumnskip}
+@findex belowcolumnskip
+after it. The default value for both of these parameters is
+@code{\bigskipamount}, i.e., one linespace.
+
+ The columns are separated by the value of the dimen parameter
+@code{\gutter}.
+@findex gutter
+The default value for @code{\gutter} is two picas.
+
+ The macros take into account only the insertion classes
+@cindex insertion classes
+defined by plain @TeX{}, namely, footnotes and @code{\topinsert}s. If
+you have defined additional insertion classes, you will need to change
+the macros which implement multi-column mode. Furthermore, the insertions
+do not respect the column widths; if you want them to, you have to
+change the way your output routine works. (Eplain uses whatever the
+current output routine is; it is not tied to @code{\plainoutput}.)

+\singlecolumn
+Now we should be typesetting in a single column, i.e., normally. The
+fingers relaxed; I snatched mine through the hole, hurriedly piled the
+books up in a pyramid against it, and stopped my ears to exclude the
+lamentable prayer. I seemed to keep them closed above a quarter of an
+hour; yet the instant I listened again, there was the doleful cry
+moaning on! ``Begone!'' I shouted; ``I'll never let you in---not if you
+beg for twenty years.'' ``It is twenty years,'' mourned the
+voice---``twenty years. I've been a waif for twenty years!'' Thereat
+began a feeble scratching outside, and the pile of books moved as if
+thrust forward. I tried to jump up, but could not stir a limb, and so
+yelled aloud in a frenzy of fright. To my confusion, I discovered the
+yell was not ideal. Hasty footsteps approached my chamber door; somebody
+pushed it open with a vigorous hand, and a light glimmered through the
+squares at the top of the bed. I sat shuddering yet, and wiping the
+perspiration from my forehead. The intruder appeared to hesitate, and
+muttered to himself. At last he said in a half-whisper, plainly not
+expecting an answer, ``Is any one here?'' I considered it best to
+confess my presence, for I knew Heathcliff's accents, and feared he
+might search further if I kept quiet. With this intention I turned and
+opened the panels. I shall not soon forget the effect my action
+produced. Heathcliff stood near the entrance, in his shirt and
+trousers, with a candle dripping over his fingers, and his face as white
+as the wall behind him. The first creak of the oak startled him like an
+electric shock. The light leaped from his hold to a distance of some
+feet, and his agitation was so extreme that he could hardly pick it up.
+``It is only your guest, sir,'' I called out, desirous to spare him the
+humiliation of exposing his cowardice further. ``I had the misfortune
+to scream in my sleep, owing to a frightful nightmare. I'm sorry I
+disturbed you.''

+Subject: A vbox underfull while using eplain.tex
+To: karl@cs.umb.edu
+Date: Wed, 10 Nov 93 11:47:39 MEZ
+
+Dear Karl:
+
+ I'd like to appreciate your kindness to put the "eplain.tex" in the public
+domain so that I can switch \doublecolumns and \singlecolumn in an article.
+After a little change in the file "column.tex" which is located at the
+subdirectory "/eplain-2.3/test" I have got an unexpected output. There is a
+"verticle underfull (Underfull \vbox ...)" at the first page. What I've done at
+the file are:
+
+1) magnify the text font at 1 step (\magnification=\magstep1)
+2) add an extra "\singlecolumn" and "\doublecolumns" after the first
+ "doublecolumn".
+
+ Would you please tell me how can I get rid of the verticle underfull and
+get the normal single- and doublecolumns output at the same page? Thank you for
+your helpness in advance!
+
+ Sincerely,
+ Jun-Jih Liang
+
+P.S. In the following two mails I attach the file "column.tex" which has
+changed by me in the first and a Postcript formated "column.ps" which is
+transformed from "column.dvi" in the second.

+A simple one, done with plain, for comparison (it should come out
+centered). Because of the way that \TeX's modes work, you should never
+leave a blank line (i.e., cause a par command) before a display. When
+\TeX\ sees a \$ in vertical mode, it switches to horizontal mode; but
+then when the display starts, it goes back to vertical mode, thus
+causing an extraneous blank line before the display. (Plain \TeX\ sets
+abovedisplayskip to about a baselineskip, so you are going to get one
+blank line from that (unless the line above the display is short, in
+which case aboveshortdisplayskip is used, which is 3pt or some such);
+but if a par intervenes between the end of the paragraph and the
+beginning of the display, you get a second one.)

+%To: karl berry <karl@cs.umb.edu>
+%
+%Karl,
+%
+%Attached is an emulation of my document. Re-iterating, (1) the title should be
+%on the first page with the abstract, and a horizontal rule should span the
+%entire first page, and (2) the second footnote is referenced in the second
+%column on third page.
+%
+%Undoubtedly I've violated some of the rules of either TeX or eplain, but I
+%don't know what.
+%
+%Again, many thanks.

+%Put \singlecolumn just one paragraph later and everything works OK.
