5.1.94 parstr
-------------
Syntax:
parstr ( ring_name )

parstr ( int_expression )

parstr ( ring_name, int_expression )
Type:
string
Purpose:
returns the list of parameters of the ring as a string
or the name of the n-th parameter where n is given by the int_expression.

If the ring_name is omitted, the basering is used, thus
parstr(n) is equivalent to parstr(basering,n).
Example:
  ring r=(7,a,b,c),(x,y),wp(2,3);
  parstr(r);
==> a,b,c
  parstr(2);
==> b
  parstr(r,3);
==> c
