12.0.11 `print_tex_form'
------------------------

print_tex_form(S)
     :  It transforms S to a string of the LaTeX format.

print_tex_form(S | TABLE=key0)
     : This function allows optional variables   TABLE

   Description:

     The global variable Print_tex_form_fraction_format  takes the
     values "auto", "frac",  or "/".   The global variable
     Print_tex_form_no_automatic_subscript  takes the values 0 or 1.
     BUG; A large input S cannot be translated.


   Example:
      print_tex_form(x*dx+1 | table=[["dx","\\partial_x"]]);

   The optional variable table is used to give a translation  table of
asir symbols and tex symbols.
