Novice Questions

Sorry for being so dense. I've tried to find the answers for these but apparantly don't know where to look.

1. How do I issue commands from my own basic programs? Are they DOS command line? For example, if I would like to turn on my receiver, and start a playlist called playlist1.pla, what do I do?

2. When using CDJ with multiple libraries, I need a way to switch audeo inputs when playing each different library. I have a switcher with 4 inputs and one output that uses ir. Assuming I can learn the ir commands, what do I do to have cdj issue a command to switch input to 1 of 4 positions based on which cd library is being used?

Thanks in advance, and my appoligies for not figuring out how to do this myself.
