 Remember that registers such as Dxx, CDxx and other internal registers, except for DSxx, return to the initial state (usually 0) after initializing the project (which happens when editing project elements - scripts, registers, connections, etc.). If such registers are used as variables to generate event triggers or conditions for executing other scripts, this can lead to a violation of the execution logic. You should consider this feature when choosing registers as input and output script variables.

+===== Differences between write function for internal/external registers =====
 There are some differences in the operation of the SetReg and WriteReg functions with respect to internal registers (Dxx, DSxx). These functions directly change the values of the internal registers inside the scan, and do not delay WriteReg writing to the next scan start. Thus, at the end of the scan, the internal register can have a value different from the one at the scan input. Then, for example, a situation is possible where:

+===== Step over trick =====
+When you need to run once your script and inspect its result in the console, you can do this as follows:
+  *make extra bit register, like "Debug step over bit"
+  *change run mode of the script being debugged - execute upon the register's (you've created in the previous step) change
