Abstract
1433119 Programmable desk top calculator HEWLETT-PACKARD CO 20 Dec 1972 [27 Dec 1971] 32756/75 Divided out of 1433117 Heading G4A With the exception of the detailed program coding the disclosure is similar to that of the British parent Specifications 1,433,117,1,433,118 and 1,433,120. The claims are directed to flag keys which are used to enter flag statements into the calculator, a flag being defined as a variable whose value is either set or clear, corresponding to one or zero respectively, and corresponds to a clear, set or test function involving flag variables in the calculator memory. The flag is used to suppress the display of an alphameric error message in response to mathematically illegal statements or arithmetic underflow or overflow.
