Abstract
An electronic calculator apparatus includes a keyboard for inputting numerical and function data, a printer for printing out on a record medium a sequence of data input by the keys and calculation results related to the data, and a printer controller for determining the content and format of the data printed out. The printer controller has the capability of recognizing when two successive function keys are actuated, and instructs the printer to print out on the record medium two successive function symbols without any numerical data symbols therebetween corresponding to symbols on the successively actuated function keys. Accordingly, an operator may study the record medium and locate amended function input data in regions where two function symbols ar juxtaposed.
