Decimal Tabulation and Text Centering

A text processing system having a keyboard, a printer, a memory, and a display includes operator selectable routines enabling the system to enter keyed text character codes into the memory, in accordance with decimal tabulation and centering modes of operation.

The operator selects a decimal tabulation instruction and keys a tabulation code into the memory, for causing escapement of the display cursor to the desired decimal point location. Subsequently, keyed text characters are entered into the memory following the tabulation code, with the first entered character code immediately adjacent the tabulation code and with the first entered character being displayed at the desired decimal point location. Printer operation is inhibited during entry of the keyed character codes into the memory.

After all of the character codes are entered, a field-end code, such as a carrier return or tabulation code is keyed. An accumulation of backspace codes equal to the printing escapement of the character codes preceding the decimal point is then entered into the memory, in storage locations succeeding the tabulation code and immediately preceding the first entered character code, after all of the character codes are moved to allow storage space for the backspace codes. Upon entry of the backspace codes into the memory, the display is responsive to the string of backspace codes to shift the displayed text to the left, so that the field is displayed with the decimal point at the desired location.

When printing is effected, the print carrier first escapes forwardly to the desired decimal point location, then backwardly a distance equal to the total accumulation of backspace codes,...
