If you want to make your own exit/dead causes you can do that in . Go to the “General”-menu and choose “Cause”. A new window will open:
In the last row in this window you will be able to enter your own dead/exit cause. First you enter a code, which can both be numbers and letters and then you enter the cause name and set the cause to “ACTIVE”. In the following columns you choose where the cause should be available as an exit/dead cause by putting checkmarks in the boxes.
If you stop using a cause you can set the status of it to "Passive" and it will no longer be available when registering causes.
If you want to reuse a number - place the cursor in the number eg. 1 - press F2 on your keyboard and rename to a code that does not exist. Now you can make a new code 1.
