Parameters can be of type: IN - read only OUT - write - no initial value, value must be supplied by procedure INOUT - read/write - new value should be supplied by procedure Additionally you can specify NOCOPY, which means the compiler "might" (to quote the documentation) pass by reference rather than by value. http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10472/subprograms.htm#i4107 (The SHAKEITALLABOUT mode was considered, but rejected :-) )
