debug Tools Cont.
-Underlines syntax errors dynamically, can be corrected before running saves time
Error Message List
-Tells you where the errors are and what corrections can be made
Crash dump/post-mortem routine
-shows that states of the variables where an error occurs
Traces
-Prints out of variable values for each statement execution within a program
Breakpoints
-Can be placed in the code and when that point is reached in the program as it runs , it stops
used to check if a program works up to certain point
Watch Window
-allows you to view how the variables change during running of the program

properties you can view and edit and alter from this window
