![]() is better suited for interactive use and easier to use for those who are not used to RPN. RPN mode programs are usually smaller and faster, while D.A.L. These keystroke programs, in addition to performing any operation normally available on the keyboard, can also make use of conditional and unconditional branching and looping instructions, allowing programs to perform repetitive operations and make decisions.Įven with indirect jumping removed, the HP 35s still supports indirect addressing, with which it is still possible to implement a Universal Turing machine and therefore the programming model of the HP 35s can be considered Turing complete.Īs in normal operation, programming can be done in either in RPN or in D.A.L. Unlike the original HP-35, the HP 35s is keystroke programmable, meaning that it can remember and later execute sequences of keystrokes to solve particular problems of interest to the user. It also features the sloped-front keys for which HP calculators (although not the original HP-35) are well known. FEATURESThe HP F2215AAB12 Programmable Scientific Calculator is one of HPs ultimate RPN programmable scientific calculators which delivers professional. Approximately 30 kilobytes of memory for programs and/or dataĪlthough the HP 35s has far more functions, processing power, and memory than the original HP-35 which it commemorates, Hewlett-Packard has attempted to give the HP 35s the look of the original HP-35 and other HP calculators of that era. ![]()
