CLASS{\protect\APLunderbar}DESCRIPTION:
{\APLbr}                                    APL2TEX implements the
{\APLbr}basic functionality needed to typeset APL
{\APLbr}documentation with \LaTeX. The basic functionality includes
{\APLbr}\begin{enumerate}
{\APLbr}             \item printing a workspace as a \LaTeX\
{\APLbr}document,                          \item a processor for merging all
{\APLbr}include files of a \LaTeX\ document            into one large
{\APLbr}file (convenient for e-mail \dots),                   \item
{\APLbr}printing an array,
{\APLbr}   \item an array in boxed representation,
{\APLbr}                \item a function in canonical representation,
{\APLbr}                             \item a function as displayed by
{\APLbr}the del-editor,                           \item a function in
{\APLbr}direct definition form,                                \item
{\APLbr}an APL expression as typed in by the user (six spaces
{\APLbr}indented),     \item and one step of a dialogue (an user input
{\APLbr}followed by the                  computer{\APLquote}s response).
{\APLbr}                                          \end{enumerate}
{\APLbr}                                                       \par

{\APLbr}
{\APLbr}                   The class APL2TEX can be easily converted
{\APLbr}to APL workspace form            and does not depend on the
{\APLbr}object oriented system. APL2TEX                 is the version
{\APLbr}for IBM{\APLquote}s APL2 interpreter under the CMS operating
{\APLbr}system.  \par
{\APLbr}
{\APLbr}                                You should always define a
{\APLbr}temporary A-disk, because some of               APL2TEX{
{\APLbr}\APLquote}s functions generate synthetic file identifiers and write
{\APLbr}      files on the A-disk without checking for existing
{\APLbr}files. Files             may be overwritten.
{\APLbr}

{\APLbr}{\bf Requirements:} \LaTeX\  and the apl.sty style file.

{\APLbr}testversion. No responsibility for any
{\APLbr} damage or any other failures is taken by the author.

 PRTEX{\protect\APLunderbar}DIALOG simulates and prints one

{\APLbr}argument of PRTEX{\protect\APLunderbar}DIALOG        is a text
{\APLbr}string     containing the APL expression normally        typed in
{\APLbr}by the user. User input is printed in        bold face, six
{\APLbr}spaces indented with           proportional        spacing. The
{\APLbr}response of the APL interpreter (if     any) is        printed
{\APLbr}with fixed spacing thus simulating a
{\APLbr}traditional type writer.
