Abstract

The internal data stream of a word processor is typically divided into text segments. Included in each text segment is a syntactic specification of the format of the text at the beginning of each unit and the text stream encapsulated in a body text vector. The format information is in structured fields known as vectors. The set of vectors declares the format state at the start of a text segment, such as, for example, the left margin and tab placements. Another name for this initial format information is carry-over-format since it is the format in effect at the end of the previous text segment. In a large or infinite page capacity of a word processor, many text segments may represent one page to the operator.

Carry-Over-Format Bypass

The internal data stream of a word processor is typically divided into text segments. Included in each text segment is a syntactic specification of the format of the text at the beginning of each unit and the text stream encapsulated in a body text vector. The format information is in structured fields known as vectors. The set of vectors declares the format state at the start of a text segment, such as, for example, the left margin and tab placements. Another name for this initial format information is carry-over-format since it is the format in effect at the end of the previous text segment. In a large or infinite page capacity of a word processor, many text segments may represent one page to the operator. Because of the number of lines displayed on the large display, there often will be two or more text segments being displayed at the same time. These text segment boundaries are for internal use only, and they are invisible to the operator. For purposes of this description, assume that there are two segments being displayed on the screen. The operator inserts a format change in segment one and changes the left margin, for example. If the text buffer manager does not change the carry-over-format in segment two, the screen will be rebuilt using the new format change until it reaches the line containing the carry-over-format. The carry-over-format left margin value in segment two will be picked up and used, and the text segment boundary will unfortunately become very visible to the operator....
