text \<open>
Isabelle supports an infinite number of non-ASCII symbols, which are
- represented in source text as @{verbatim \<open>\\<close>}@{verbatim "<"}\<open>name\<close>@{verbatim ">"} (where \<open>name\<close> may be any identifier). It
+ represented in source text as \<^verbatim>\<open>\\<close>\<^verbatim>\<open><\<close>\<open>name\<close>\<^verbatim>\<open>>\<close> (where \<open>name\<close> may be any identifier). It
is left to front-end tools how to present these symbols to the user.
The collection of predefined standard symbols given below is
available by default for Isabelle document output, due to
- appropriate definitions of @{verbatim \<open>\isasym\<close>}\<open>name\<close> for each @{verbatim \<open>\\<close>}@{verbatim "<"}\<open>name\<close>@{verbatim
- ">"} in the @{verbatim isabellesym.sty} file. Most of these symbols
+ appropriate definitions of \<^verbatim>\<open>\isasym\<close>\<open>name\<close> for each \<^verbatim>\<open>\\<close>\<^verbatim>\<open><\<close>\<open>name\<close>\<^verbatim>\<open>>\<close> in
+ the \<^verbatim>\<open>isabellesym.sty\<close> file. Most of these symbols
are displayed properly in Isabelle/jEdit and {\LaTeX} generated from Isabelle.
Moreover, any single symbol (or ASCII character) may be prefixed by
- @{verbatim "\<^sup>"} for superscript and @{verbatim "\<^sub>"} for subscript,
- such as @{verbatim "A\<^sup>\<star>"} for \<open>A\<^sup>\<star>\<close> and @{verbatim "A\<^sub>1"} for
+ \<^verbatim>\<open>\<^sup>\<close> for superscript and \<^verbatim>\<open>\<^sub>\<close> for subscript,
+ such as \<^verbatim>\<open>A\<^sup>\<star>\<close> for \<open>A\<^sup>\<star>\<close> and \<^verbatim>\<open>A\<^sub>1\<close> for
\<open>A\<^sub>1\<close>. Sub- and superscripts that span a region of text can
- be marked up with @{verbatim "\<^bsub>"}\<open>\<dots>\<close>@{verbatim
- "\<^esub>"} and @{verbatim "\<^bsup>"}\<open>\<dots>\<close>@{verbatim "\<^esup>"}
+ be marked up with \<^verbatim>\<open>\<^bsub>\<close>\<open>\<dots>\<close>\<^verbatim>\<open>\<^esub>\<close> and \<^verbatim>\<open>\<^bsup>\<close>\<open>\<dots>\<close>\<^verbatim>\<open>\<^esup>\<close>
respectively, but note that there are limitations in the typographic
rendering quality of this form. Furthermore, all ASCII characters
and most other symbols may be printed in bold by prefixing
- @{verbatim "\<^bold>"} such as @{verbatim "\<^bold>\<alpha>"} for \<open>\<^bold>\<alpha>\<close>. Note that
- @{verbatim "\<^sup>"}, @{verbatim "\<^sub>"}, @{verbatim "\<^bold>"} cannot be combined.
+ \<^verbatim>\<open>\<^bold>\<close> such as \<^verbatim>\<open>\<^bold>\<alpha>\<close> for \<open>\<^bold>\<alpha>\<close>. Note that
+ \<^verbatim>\<open>\<^sup>\<close>, \<^verbatim>\<open>\<^sub>\<close>, \<^verbatim>\<open>\<^bold>\<close> cannot be combined.
