What needs to be done (pascal)?

Question

Pascal

"Write a program for the information service of the railway station.
The program should issue certificates about the availability of tickets for sleeping,
compartment and second-class cars for all trains of the current month. It should
be possible to display all available
tickets for a particular train, as well as search for the desired train. When
the program is closed and restarting it, ticket information should be
saved"
What should I do (more)?
Are there ready ones?

Answer 1

A properly asked question contains a fair amount of the answer. Your so contains the entire answer. You need to write a program. This is not a site for doing assignments for lazy students.

Answer 2

You yourself try to do, and what is not clear we will help. No one will do the task for you :)
