+ Calc will try to guess an appropriate language based on the major mode

+ in @code{latex-mode}, for example, Calc will set its language to 
address@hidden
+ Similarly, Calc will use @TeX{} language for @code{tex-mode},
+ @code{plain-tex-mode} and @code{context-mode}, C language for
+ @code{c-mode} and @code{c++-mode}, FORTRAN language for
+ @code{fortran-mode} and @code{f90-mode}, Pascal for @code{pascal-mode},
+ and eqn for @code{nroff-mode}.  These can be overridden with Calc's mode
+ changing commands (@pxref{Mode Settings in Embedded Mode}).  If no
+ suitable language is available, Calc will continue with its current language.

  Calc normally scans backward and forward in the buffer for the
  nearest opening and closing @dfn{formula delimiters}.  The simplest
  delimiters are blank lines.  Other delimiters that Embedded mode

  When you enable Embedded mode for a formula, Calc reads the text

  Note that Calc does not change the current language mode according
! to what it finds.  Even though it can read a address@hidden formula when
  not in address@hidden mode, it will immediately rewrite this formula using
! whatever language mode is in effect.  You must then type @kbd{d L}

  @section Mode Settings in Embedded Mode
  
  @noindent
+ The mode settings can be changed while Calc is in embedded mode, but
+ will revert to their original values when embedded mode is ended
+ (except for the modes changed while the mode-setting mode was

  Embedded mode has a rather complicated mechanism for handling mode
  settings in Embedded formulas.  It is possible to put annotations
  in the file that specify mode settings either global to the entire
