Description

the command sequence C without affecting the global aliases.

    GB.Man(<quotes>Alias In</quotes>);
  EndAlias;
============ Alias In =============
   ---&gt; Output suppressed &lt;---
-------------------------------
  I := Ideal(x^2, y);
  G := Res(I);
  GB.GetBettiMatrix(I);     -- the global alias GB is unaffected
   ---&gt; Output suppressed &lt;---
-------------------------------
