I need some advice on this pseudocode problem?

I am thinking during this problem for a time, and I am lost.I only have someone to make sure me what should be done right here.Don’t actually give me the answer.Here is a problem.

Design an opportunity that will probably read any file associated with product information, each containing the idea number, the idea name, the amount sold this holiday season and the amount sold last year.The program would be to produce a product list showing the idea number, the idea name, as well as increase or reduction in the volume sold 2010 for each and every item.

This is what I obtained so far.

Process_Product_records
Examine Product_records

That’s it! Because I merely don’t recognize repeat until eventually structures.Remember to, help me understand this stuff.

Basically, it repeats some sort of block of code until a specific condition is definitely met.As an example,

Repeat
Display Simpsons Reruns
Right until Time = FIVE:00pm
Display Family Guy

So basically, this program will continue showing simpsons reruns right until 5:00, then it is going to show Loved ones Guy.
