Title: Tabulation control system having two electronic tab racks
IPC: G06F3/12
Filed: 1979-02-26
Abstract: A system having two tab racks for controlling playout of sequentially stored text columns in a side-by-side format. During input keying set up of a job, desired tabs are set in a text tab rack and stored in a text buffer along with the text. These tabs will be in control for following keyed text.
