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).
