Abstract
A method of, and system for, efficiently managing a temporary base line move operation to obtain an aesthetically pleasing and understandable equation and sub/super-script printout, and avoid excessive keying and indexing calculations. A single control is built based on an established base line. Included in the control are direction of move and magnitude of move from the established base line to the temporary base line. Following printing on the temporary base line, the control can be used to return to the established base line. The major advantages are limited coding, the magnitude of the move is independent of line spacing, and a return to the established base line can be without knowledge of the move magnitude.
