  | ### 5.1.126 quote `Syntax:` `quote (` expression `)` `Type:` none `Purpose:` prevents expressions from evaluation. Used only in connections with write to ssi links, prevents evaluation of an expression before sending it to an other SINGULAR process. Within a quoted expression, the quote can be "undone" by an `eval` (i.e., each eval "undoes" the effect of exactly one quote). `Example:`
        link l="ssi:w example.ssi";
        ring r=0,(x,y,z),ds;
        ideal i=maxideal(3);
        ideal j=x7,x2,z;
        option(prot);
        // compute i+j before writing, but not std
        write (l, quote(std(eval(i+j))));
        close(l);
        // now read it in again and evaluate:
        read(l);
      ==> try HC in ring over ZZ/32003
      ==> [1048575:1]1(12)s2(11)s3(10)--s(7)sH(5)7
      ==> product criterion:4 chain criterion:0
      ==> HC(3) found
      ==> [1048575:1]1(8)s2(7)s3(6)--s(3)s(2)--
      ==> product criterion:4 chain criterion:0
      ==> _[1]=z
      ==> _[2]=x2
      ==> _[3]=xy2
      ==> _[4]=y3
        close(l);
