Need some quick points on the differences between developing in VFP and Oracle. Forget the database issues, I need to focus on Oracle Forms and their report writer. For example,

I can turn on/off selected menu items in VFP, can I do that in Oracle.
There is much flexibility in VFP code when manipulating the User Interface. Does that flexibility exist through PL/SQL for Oracle forms?
How does one code a complex process in Oracle, one that would have potentially thousands of lines of data manipulation code?
Complex reports are easy in VFP because we can define a class or write a program to accomodate all data manipulation prrior to creating a final cursor for a report. Can Oracle do that?

Thanks,
Steve
