Define
Catalog
 > 
Define Var  = Expression
Define Function(Param1, Param2, ...) = Expression
Defines the variable Va r or the user-defined function Function.
Parameters, such as Param1, provide placeholders for passing 
arguments to the function. When calling a user-defined function, you 
must supply arguments (for example, values or variables) that 
correspond to the parameters. When called, the function evaluates 
Expression using the supplied arguments.
Va r and Function cannot be the name of a system variable or built-in 
function or command.
Note: This form of Define is equivalent to executing the expression: 
expression & Function(Param1,Param2).
