Q: When debugging, while the execution of a procedure's code is paused, you can view the contents of controls and variables that appear in the highlighted statement, as well as in the statements above it in the procedure.

Q: Some logic errors occur as a result of calculation statements that are correct syntactically, but incorrect mathematically.

Q: Unlike logic errors, syntax errors are much more difficult to find because they do not trigger an error message from the Code Editor.

Q: The Code Editor detects most syntax errors as you enter the instructions.

Q: Logic errors are the easiest to find.

Q: Program bugs typically are caused by either syntax errors or logic errors.

Q: As the amount of code increases, so does the likelihood for errors.

Q: One advantage of variables and named constants is that their use requires fewer lines of code.

Q: You can use variables to store the values of processing items, which do not appear in a user interface.
