The problem is that we don't know what you don't know. Stepping is
accomplished by decoding an instruction to find out where the next
instruction will be, setting a temporary breakpoint there, and
restarting the program. Stepping one line is stepping until the line
changes. What is it you want to know that isn't obvious?
