Hiding PL/SQL Code
You can deliver your stored procedures in object code format using the PL/SQL Wrapper. Wrapping your PL/SQL code hides your application internals. To run the PL/SQL Wrapper, enter the WRAP command at your system prompt using the following syntax:
WRAP INAME=input_file [ONAME=ouput_file]
For complete instructions on using the PL/SQL Wrapper, see the PL/SQL User's Guide and Reference.
