5.1.134 varstr
--------------
Syntax:
varstr ( ring_name )

varstr ( int_expression )

varstr ( ring_name, int_expression )
Type:
string
Purpose:
returns the list of the names of the ring variables as a string
or the name of the n-th ring variable, where n is given by the
int_expression.

If the ring name is omitted, the basering is used, thus
varstr(n) is equivalent to varstr(basering,n).
Example:
  ring r=0,(x,y,z),dp;
  varstr(r);
==> x,y,z
  varstr(r,1);
==> x
  varstr(2);
==> y
