thanx for your reply guys, i'm developing one student project which does not involves any applications, i'm not using forms or any API, just we are using plain plsql packages and procedures to brief our students.

We are doing a simple bank project
where we have modules viz., withdraw,deposit,account opening, and so on.

I wrote individual procedures for all these modules, but then i need to prompt users for giving inputs.

for eg, in one module we will have all the menus

like 1. account opening

2. withdraw

3. deposit and so on..

so when the users selects 1 from the menu it would execute account opening procedure which in turn would have to accept some values during execution from the user, for eg Execute withdraw; it should accept two values account number and amount, and all this should go on without user intervention. in other words the user is permitted to enter values and get the respective output. looking forward for your inputs!! thanks in advance.
