Markers Check_Protection
Check_Protection markers can be used to check the integrity of the protection code. If the protection code is corrupted, the code inside the marker will not be executed, and if the protection is OK, the code inside the marker will be executed. This is a very good and useful way to hide the "weak" points from crackers, for example, the key check routine, etc. can be placed inside these markers.
