Pascal - using mouse

Hello guys!

I am new at the forum, but I have read many posts here and I will be really glad if you help me :)

I need to use mouse in my program so I need mouse.tpu file. Can you give me a link to download it?

And I have read how to initialize mouse (initMouse,doneMouse, ect.), but I will be really happy if you pose some very simple example on how it works (if you post a source code for a program which writes 'Click' at position x,y where I have clicked)

Thank you so much!
