`rtostr'
--------

rtostr(OBJ)
     :: Convert OBJ into a string.

RETURN
     string

OBJ
     arbitrary

   * Convert an arbitrary object OBJ into a string.

   * This function is convenient to create variables with numbered (or
     indexed) names by converting integers into strings and appending
     them to some name strings.

   * Use `strtov()' for inverse conversion from string to indeterminate.

     [0] A=afo;
     afo
     [1] type(A);
     2
     [2] B=rtostr(A);
     afo
     [3] type(B);
     7
     [4] B+"1";
