Using the debugger

This recipe will show you how to use the debugger to examine the code that is currently executing. We will demonstrate how to go through the code line-by-line and watch how values and objects change.

How to do it...

1. Create a new codeunit from Object Designer.

2. Add the following global variable:

   Name	Type	Subtype
   Customer	Record	Customer

3. Add the following global text constant:

   Name	ConstValue
   Text001	Matt Traxinger

4. Add a global function called ChangeCustomerName.

5. The function should take in the following parameter:

   Name	Type	Length
   NewName	Text	50

6. Add the following code to the function:

   Customer.Name := NewName;
   

7. Add the following code to the OnRun trigger:

   Customer.FINDFIRST;
   ChangeCustomerName(Text001);
   Customer.VALIDATE("Post Code");
   

8. Save and close the codeunit.

9. From the Tools menu in the NAV client select Debugger | Active (Shift + Ctrl + F11).

10. From the Tools menu in the NAV client select Debugger | Breakpoint on Triggers (Shift + Ctrl + F12).

11. Run the codeunit...
