A.2 PL/SQL Source Text Wrapping Guidelines

• Wrap only the body of a package or type, not the specification.

  Leaving the specification unwrapped allows other developers to see the information needed to use the package or type (see Example A-5). Wrapping the body prevents them from seeing the package or type implementation.

• Wrap files only after you have finished editing them.

  You cannot edit wrapped files. If a wrapped file needs changes, you must edit the original unwrapped file and then wrap it.

• Before distributing a wrapped file, view it in a text editor and ensure that all important parts are wrapped.
