Hello again, here am I to ask another question to the net, which
helped me so much through all my rough times.

This time it's about the kernal routines.
(I'm into machine-code the last time)

For instance :
		The kernal routine to output one character is CHROUT
		and is located at $FFD2.
		I already knew that.
		I also know that you have to put the ASCII-code for
		the character you want to print in the accumulator.

		I found this out by just looking at listings in
		magazins and listings from the net.

My question is this :
			Can someone post some kernal routines that
			are handy or absolutely needed to make the
			life of a machine-code programmer easier ?

			Maybe someone would post some hints or so
			that he or she found were very usefull to
			him or her at the time he or she learned
			to program in machine-code.
			( The programming itself is no problem,
			  but the kernal has so much secrets for
			  me that I want to find out. )


				Thanks in advance,
