The area for the triangle is 500. Pressing the IENTER I key will execute the same expression again. If the II PLAY BACK II key is pressed while the result is being displayed, the AER menu wil be displayed. Error Messages (1) AER format error CD The expression was entered in an incorrect format (parameter + expression). ® ")=" is missing after "F(". Press the IC.CE I key to display the title and expression. Position the cursor, and correct the expression. (2) AER memory over An attempt was made to enter more than 20 expressions. The AER menu will be displayed. (3) Syntax error An invalid expression or variable has been entered. (4) Type mismatch The type of the specified data does not match. (5) Division by zero An attempt was made to divide by zero. (6) Overflow The calculated result exceeds the calculation range. (7) Illegal function call An illegal operation was attempted. (8) Data out of range The specified value exceeds the allowable range. (9) Out of memory Not enough memory free area is available. Press the IENTER Ikey to return to the RUN mode, and delete unnecessary data and/or programs. Errors (3) to (8) may occur when entering values during the "1. EXECUTE" operation. (1) If an invalid value is entered and an error occurs, press the IC·CE I key and re-enter the correct value. (2) If an invalid expression is registered and an error occurs, press the IC.CE I key to display the title and expression where the error occurred. Correct the expression. 74 6. STAT MODE The Card can perform statistical and regression calculations on one or two variables. With statistical calculations, you can obtain mean values, standard deviations, and other statistics from sample data. Regression calculation determines the coefficients of linear regression formulas or estimated values from sample data. Selecting and Cancelling the STAT Mode Selecting the STAT mode Press the II STAT I key to display the STAT menu as shown. Press the [ I J key to select single-variable statistical calculations, the D=:J key to select two-variable statistical calculations or the CIJ key to specify the display and print format (single- or double-precision). Note: If the STAT mode is not entered when the I STAT II key is pressed, or if "Out of memory" appears, there is not enough free area. Press the IENTER I key to return to the RUN mode, and delete unnecessary data and programs from the memory. Cancelling the STAT mode o=J Press the key to exit the STAT mode. The Card returns to the BASIC mode. I':UN t10IJE ." ... 75
