Debugging
At certain points, our program may produce unpredictable errors or invalid output. In that case, we need to trace what went wrong, by debugging each line of code. But before that, there are some general debug commands we need to know.
Single-stepping a program means debugging per line of code. There are two modes to single step: step into and step over. During debugging, when the line being debugged is a CALL instruction, single-step debugging continues in the subroutine when a step into mode is used. The step over mode, however doesn't enter the subroutine, but rather lets the subroutine finish up running and the single step continues on the line after the CALL instruction. See the following comparison:
| Step into | Step over ... |
