I remember that it used to be if you set your profile top on with a drilling tool, it would give you a G99, or return to Z-clear, but if you set the tool without a profile top, it would be a G98, or Z-check location.  However, I have a file that I cannot seem to do that on, and the only thing I have found so far is .smf question 83 which sets a fixed distance above z-level as the z-check distance. 
Any help out there?
