End project based upon Macro value

[lherz]

How do I quit a project from within a step?

Actually I do not just want to quit the project but fail a step that will then call a specific fail step to send an appropriate e-mail before quitting.

I am testing for the existence of data in a macro, and have that piece working, but just seem to be drawing a blank on how to get the step to conditionally fire the fail steps to send the e-mail and quit gracefully.
