  | ### 7.8.10 rightstd (letterplace) `Syntax:` `rightstd(` ideal_expression`)`; `rightstd(` module_expression`)`; `Type:` ideal or module `Purpose:` Compute a right Groebner basis of the set of generators of the input ideal/module. `Note:` It is also effective in factor rings. `Example:`
      LIB "freegb.lib";
      ring r = 0,(x,z),dp;
      ring R = freeAlgebra(r,7);
      ideal I = z, x*z, x*x*z;
      rightstd(I); // a right GB of I in K<x,z>
      ==> _[1]=z
      ==> _[2]=x*z
      ==> _[3]=x*x*z
      qring Q = twostd(x*z); // now we change to the factor algebra modulo x*z
      ideal I = imap(R,I);
      rightstd(I); // a right GB in a factor algebra
      ==> _[1]=z
      reduce(I,twostd(0)); // an explanation for the latter
      ==> _[1]=z
      ==> _[2]=0
      ==> _[3]=0
