Dear Mr. Arjang, I don't think accessing an unassigned variable is the cause of the problem. To ensure that, this time I press that button 3 times with the same options, every thing was ok, but the next time exactly with the same option "access violation" occurs. if the problem is concerned with accessing something that is not assigned, the program shouldn't continue the calculations 3 first times. whould u please explain me how can I recycle my used variables (they r mostly arrays of doubles and strings) at the end of that routine 2 ensure that they r free 4 the next calculations? thanks in advance, Roshanak
