MORE INFORMATION

BeginPackage is typically used at the beginning of a Mathematica package.

BeginPackage resets the values of both $Context and $ContextPath.

The interpretation of symbol names depends on context. BeginPackage thus affects the parsing of input expressions.

Basic Examples (1)

Commands to define a simple package:

The context for symbol creation has been changed to square`:

The context path for symbol lookup includes square`:

Here are the commands defining the function in the package:

Restore the context, but leave square` on the context path for symbol lookup:

Since EndPackage leaves square`square on the context path, the function defined is visible:

Get the square of 12:

EndPackage Begin
