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.
