Can PL/SQL Acccept an inputted variable?

My "Query" refers to the ability to input variables in a PL/SQL Procedure.

Basically I am able to to input variables using the normal method
Exec procedure(variable1, variable2)

However I want to know if it is possible to code in such a way that the user inputs a variable when requested by the code:
For instance when the procedure is run, I want the DBMS to ask questions and accept the variables I put in to answer them
Sort of like the DBMS_OUTPUT but in reverse.
DMBS_INPUT perhaps??

Example:
SQL> Insert First Name?
SQL>

Thank you for any help with this...This is not possible...normally the database server running far away from the user and can't interact directly with him/her.
For such inputs you must implement a frontend...maybe an ms-access frontend can solve your problem.|||The project is an all Oracle affair, hopefully Oracle correct this problem because it would be handy to have this feature.
Thanks for your help and time Bart71|||If you are allowing your user to input directly through SQL Plus, I would suggest giving them a script to run rather than having them execute a package/procedure. Create a "test.sql" file as follows:

accept a prompt "Input First Name?"
execute my_procedure( '&&a' );

You can add whatever else you need; after that, from SQL Plus they would type:

SQL> @.test.sql

However, HIGHLY suggest having users go through a program interface rather than directly through SQL Plus...
