I have a table of strike and dip symbols in MapInfo. I need to export these to ArcView 
but ArcView starts the symbol at a different angle and rotates in the opposite 
direction that MapInfo does. (ArcView starts at horizontal 0 degrees and rotates 
counterclockwise while MapInfo starts at vertical 90 degrees and rotates clockwise.) I 
figured out the formula to transform the coordinates and had to do it by quadrant, 
which means I had to query and update in 4 separate segments. My question is this, is 
there a way to do this in one mass update?

Here are the formulas that I used to get the correct ArcView strike angle
Strike          Formula
0-90            180 + (90 - Strike)
91-180          90 + (180 - Strike)
181-270         (270 - Strike)
271-360         270 + (360 - Strike)
