4.4.1 def declarations

Syntax:
def name = expression ;

Purpose:
defines an object of the same type as the right-hand side.

Default:
none

Note:
This is useful if the right-hand side may be of variable type as a consequence of a computation (e.g., ideal or module or matrix). It may also be used in procedures to give the basering a name which is local to the procedure.

Example:
 
  def i=2;
  typeof(i);
==> int

See typeof.
