Now while it's perfectly fine to use the forum, and spent a lot of time waiting for answers => there is a quicker, better way: google
And as I understand you are learning (maybe even teaching yourself) how to program, let me just say that programing is not just a few keywords in some language.
One of the points that makes a programmer is the ability to find information:
google: delphi clipboard
FreePascal/Lazarus are very similar, so very often you can use the results the same way.
First page I got was:
http://delphi.about.com/od/vclusing/a/tclipboard.htmAnd if there is any diff in freepascal, it gives you enough keywords to search the lazarus source for examples.
