    摘要: A modular read-write and read-only memory unit capable of employing both direct and indirect decimal and symbolic addressing, a central processing unit capable of performing both serial binary and parallel binary-coded-decimal direct and indirect memory register arithmetic, and an input-output control unit capable of bidirectionally transferring information between the central processing unit and a number of input and output units are controlled by a microprocessor included in the central processing unit. The input and output units include a keyboard input unit, a magnetic card reading and recording unit capable of bidirectionally transferring information between an external magnetic card and the read-write memory unit, and a solid state output display unit capable of displaying three lines of numeric information. The memory, central processing, input-output control, input, and output units are employed to provide an adaptable programmable calculator that may be operated manually by the user from the keyboard input unit or automatically by a program stored in the read-write memory unit. The calculator may also be employed to load programs into the read-write memory unit from the keyboard input unit, to separately transfer either data or programs bidirectionally between the read-write memory unit and an external magnetic card, and to code programs stored in the read-write memory unit as being secure when they are transferred to an external magnetic card, thereby preventing users of the calculator from re-transferring them to an external magnetic card or obtaining any indication of the individual program steps once they are reloaded into the calculator.

The keyboard input unit includes a plurality of operand keys and a plurality of operator keys for entering algebraic statements specifying selected arithmetic operations, including relational operations, into the calculator. The operations specified in a particular algebraic statement are processed in accordance with a predetermined hierarchal priority of operations, all relational operations performed last. In the event an algebraic statement being processed specifies a plurality of operations having the same hierarchal priority, that plurality of operations is processed in the order in which they were specified during entry of that algebraic statement.

The memory, central processor, and input-output control units are controlled by a microprocessor included in the central processing unit. A keyboard input unit with a plurality of sections capable of being defined by plug-in read-only memory modules and stored programs added by the user, a magnetic card reading and recording unit, a solid state output display unit, and an output printer unit are included among the input and output units. The calculator employs a high level algebraic keyboard language permitting the user to enter a line of one or more alphameric statements into the calculator from the keyboard input unit while visually observing an alphameric display of the line being entered to check for errors therein, permitting the user to cause the entered lines to be immediately executed by the calculator and/or stored as part of a program within the memory unit, and permitting the user to subsequently recall the executed and/or stored line, so that it may be reinspected, reevaluated and if necessary, edited and executed or reexecuted. The calculator also employs a compiler for converting each line entered into the calculator in the high level keyboard language into a past-fix polish code and an uncompiler for regenerating in the high-level keyboard language any entered line converted to the post-fix polish code. Both the compiler and the uncompiler operate on a line-by-line basis.

The calculator includes a multiplicity of programmable boolean flag variables that may be designated from the keyboard input means and employed as part of an alphameric statement. Selected ones of the boolean flag variables may be manually set from the keyboard at any time during execution of a program stored in the read-write memory. A dedicated one of the boolean flag variables is automatically set by the calculator when a mathematically incorrect program statement or an arithmetic underflow or overflow is encountered during program execution.
