I have been reading about packages, and may need to create one. I understand that the package body may not be necessary, but my question is, is the package SPEC always necessary? What if every function and procedure to be used in the package should be private to the body? What then do you put in the spec? Instructions also say to put as little as possible in the spec, as it is accessible to any other module. What would the syntax look like for creating a package with nothing in the spec portion?
Thanks for your help & enlightenment
