Erik, Look at the TYPE() function. It returns the type of variable you pass it. For example: If you wanted to check to see if a variable was logical you would have the following syntax... STORE .F. TO lTest IF TYPE(lTest)='L' ? 'Variable is logical' ELSE ? 'Variable is something else' ENDIF The FoxPro helkp file should give all the details on the different types returned.
