See
 Ssi links;
 eval;
 write.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);
==> [65535:1]1(12)s2(11)s3(10)--s(7)s(6)-----7-
==> product criterion:4 chain criterion:0
==> _[1]=z
==> _[2]=x2
==> _[3]=xy2
==> _[4]=y3
  close(l);
