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. First create a new codeunit from Object Designer.

2. Then add the following global variable:

   Name	Type	Subtype
   Customer	Record	Customer

3. We need to add the following global text constant as well:

7. Add the following code to the OnRun trigger:

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

9. Now from the Tools menu in the NAV client, go to Debugger | Debug Session (Shift + Ctrl + F11).

10. You should see the currently running session list:
