This is probably driver-dependant, and you don't say what kind of program
you're looking at, so it's hard to infer. The disk driver, for example, uses a
CSCode of 6 as an instruction to erase the disk. I don't think that's what
your piece of code was doing, because the CSParam field was not filled in
correctly. (The disk driver wanted an integer in CSParam.)
