Abstract
For underlining a text section a command is typed both before and after the text section in the typing sequence, which command causes the storing of position values in two registers. The underlining is then performed underneath the already entered characters. A command for line advance, facultatively in connection with returning the printing head to a left position, ensures that the underlining will be performed prior to the line advance, but that the conditions for the underline will be retained also for the next line.
Claims5
A method for controlling the typing position of a processor-controlled typewriter or similar machine for automatically underlining a text section whose characters can be stored in a memory where the beginning of the text section to be underlined is marked by entering an underline command and the end of said text section is marked by entering an underline end command, said underlining being performed upon entry of said underline end command, said method comprising the steps of:
- storing, after the entry of an underline command, in a first register the horizontal position of the next character to be typed in the current text;
- activating a memory search after the entry of an underline end command, said memory search searching for the last character typed in the current text, and upon finding the last character, storing its horizontal position in a second register;
- setting the typing position to one of the stored horizontal positions;
- producing underlining by automatic stepwise advance of the printing position to the other stored horizontal position;
- and setting the printing position to the horizontal position following the underlining.
