: I'm interested in writing programs, perhaps along the lines of an IRC chat program. I was wondering where I could find online manuals and/or references for this type of things.
You mean a reference of using sockets? There are lots on Google (what flavour of Pascal are you using? If it's an old DOS based one it'll be fairly difficult)
If you mean an IRC reference, it's RFC 1459 and you can find it at www.rfc-editor.org
