Description

The CALCULATOR command displays a calculator that can be used to perform addition, subtraction, multiplication, division and percentage operations entered using the keyboard.

The calculator is operated by pressing the appropriate mathematical operators and digits on the keyboard. Percentage calculations are performed by loading the value to be calculated before entering the percentage. If the value is already displayed in the calculator, press the '=' operator, then press, for example: '50 % =' to calculate fifty percent of that value. If the value is not already displayed in the calculator, type for example '2000 =' to indicate that you are going to calculate a percentage of two thousand, then enter the percentage amount followed by the '=' operator. if the [EXIT/SAVE] key is pressed the MENUITEM() function will return the result from the CALCULATOR as a character string. The VAL() function can be used to convert a character string to a numeric. If the [ABANDON] key is pressed, MENUITEM() will return a null string.

When editing a numeric field, pressing the [HELP] key displays the CALCULATOR. If you save the result of the currently displayed calculation, using the [EXIT/SAVE] key, then the value is returned to the field.
