Abstract: An approach is provided for completing a decision logic. For statements in a syntax tree of the decision logic and using a symbolic execution technique, path expression(s) that refer to respective input object(s) are identified. A statement in the decision logic is detected that modifies an attribute value of a path expression included in the path expression(s) and that refers to an input object included in the input object(s). A copy instruction is inserted as a new node in the syntax tree so that the attribute value of the path expression is a copy of the input object. Responsive to inserting the copy instruction, the path expression is prevented from modifying the input object.

Abstract: A method, device, and/or computer program product operates a touch-screen device. One or more processors detect a first moving touch on a touch-screen, where the touch-screen is able to detect a presence of the first moving touch but is not able to detect an amount of pressure being applied by the first moving touch. The processor(s) detect a simultaneous second moving touch on the touch-screen, and detect a line being drawn on the touch-screen by the first moving touch. The processor(s) calculate a calculated pressure for the first moving touch based on a distance on the touch-screen between the first moving touch and the second moving touch while the line is being drawn on the touch-screen by the first moving touch, and then adjust a thickness of the line being drawn on the touch-screen by the calculated pressure for the first moving touch.

Abstract: A method, device, and/or computer program product operates a touch-screen device. A first touch at a location on a touch-screen is detected. A second touch on the touch-screen, which occurs simultaneously with the first touch on the touch-screen, is detected. A pressure of the detected second touch is calculated and assigned to the detected first touch. A specific touch-screen output is generated according to the location and assigned calculated pressure of the detected first touch.
