Help!! loop for current procedure

Question

I have a procedure which creates tickets to be printed. However I would like to amend this procedure so that the user can input the number of tickets s/he will be printing and then loop through my current procedure to generate them all at once.
I have been staring at this for 30 min and decided to post. It is probably glaringly obvious, but I am in need of help.
TIA

Have you found a solution to this issue?
If not then are the values of the parameters going to change for each loop iteration?
What environment is the procedure executed in? i.e. SQL*Plus, Forms, etc..
