Boolean operations with Adaption Registers
User's Guide contains the description of the operations which can be used through Adapt>Manage panel. However, the names of these operations ("Mask" "Combine" "Invert" "Exchange") are not selfexplanatory and sometimes confusing for mathoriented users; very often, users ask what is the combination of operations which have to be done to achieve a certain boolean operation like "Intersection", "Union", "Subtraction", "Complementary" of sets. The following table shows which operations from Adapt>Manage are to be used in order to perform a certain boolean operation with adaption registers A and B. Boolean Operation >>>>>>>>>>> Equivalent Actions in Adapt>Manage ________________________________________________________ CEA = E  A (complement of A wrt E) >>>>>>> Change Type on A (to mask), then Invert A ___________________________________________________________ A È B (A unite with B) >>>>>>>>>>> Combine A and B _________________________________________________________________ A Ç B (A intersect with B) >>>>>>>>> Change Type on B (to mask), then Combine A and B __________________________________________________________________________ A  B (A minus B) >>>>>>>> Change Type on B (to mask), then Invert B, then Combine A and B
