The easiest way to create a string is, as illustrated in the introduction,
to enclose a text in double-quotes or single-quotes.  It is however
possible to create a string without actually writing a text.  The
function blanks creates a string of a given length consisting
only of blank characters (ASCII code 32).
Return a string of n blanks.
For example:
blanks (10);

     ⇒
      Attr Name        Size                     Bytes  Class
      ==== ====        ====                     =====  =====
           ans         1x10                        10  char
