   Convert an arbitrary object @var{obj} into a string.
   @item
   This function is convenient to create variables with numbered
   (or indexed) names by converting integers into strings and appending them
   to some name strings.
   @item
   Use @code{strtov()} for inverse conversion from string to indeterminate.

   Convert a string that is valid for an indeterminate into an indeterminate
   which have @var{str} as its print name.
   @item
   The valid string for an indeterminate is such a string that begins
   with a small alphabetical letter possibly followed by any string composed
   of alphabetical letters, digits or a symbol @samp{_}.
   @item
   Use the command to create indeterminates dynamically in programs.
