Software Deployment

I want to set up some custom exit codes that I can use to force multiple Success codes in my SMS reports. For example: Check the value of a current user registry key and depending on the value set a different exit code for each. This would ease data gathering for us. Has anyone here done something similar?

exitcode x = "apple"
exitcode y = "orange"
exitcode z = undefined or other[/blockquote]
