摘要： An adaptable programmable calculator is provided by employing modular read-write and read-only memory units capable of being expanded to provide the calculator with additional program and data storage functions oriented towards the environment of the user, a central processing unit, and an input-output control unit capable of bidirectionally transferring information between the memory or central processing units and a number of input and output units. The memory, central processor, and input-output control units are controlled by a microprocessor included in the central processing unit. The input and output units include 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 capable of bidirectionally transferring information between an external magnetic card and the calculator, a solid state display unit capable of displaying every alphabetic and numeric character and many other symbols individually and in a line of one or more alphameric statements, and a printer unit capable of printing on thermally sensitive paper every alphabetic and numeric character and many other symbols individually and in alphameric statements or messages. The keyboard input unit includes a MINUS arithmetic operator key that initiates either the unary minus function or the subtraction function, as the context of an entered algebraic statement employing the MINUS arithmetic operator requires.

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 keyboard input unit includes a display control key for entering a DISPLAY statement into the calculator and an execute control key for initiating execution of a line of alphameric statements entered into the calculator. The DISPLAY statement may be manually or programmably employed to cause the calculator to display the results of arithmetic expressions, alphameric messages, or the contents of any memory register without thereby altering the contents thereof. By means of fixed point and floating point control keys, the user may manually or programmably designate either fixed point or floating point notation for all subsequently displayed data. The notation currently in effect may be altered by the user during program execution by simply actuating either the fixed point or floating point control key.

Programs, data, or a combination thereof may be transferred between the calculator read-write memory and an external magnetic card. The keyboard input unit includes LOAD and RECORD keys for entering statements into the calculator read-write memory to control operation of the magnetic card reading and recording unit during execution of a program stored in the calculator read-write memory. Programs transferred from the calculator read-write memory to an external magnetic card contain an indication of the current plug-in read-only memory module configuration of the calculator. Subsequent loading of a program from an external magnetic card at a time when the plug-in read-only memory module configuration of the calculator is different generates an error message for the user. A message is visually displayed to request that the user insert an additional magnetic card during those loading and recording operations involving the transfer of a large program or block of data whose size exceeds the storage capacity of a single magnetic card.
