Abstract

This article relates to the communication of mid-line keyboard changes such as type style changes in OCL (Operator Control Language) which is used in the communication between many word processors and other processors. All conventional OCL commands must be preceded by an OCL delimiter which has to be a line or page end code. Thus, in order to communicate mid-line changes, it was necessary to define a new OCL delimiter which was not a page end or line end code. The present expedient is directed to such a definition.

Communication of Mid Line Keyboard Changes in Communicating Word Processors

This article relates to the communication of mid-line keyboard changes such as type style changes in OCL (Operator Control Language) which is used in the communication between many word processors and other processors. All conventional OCL commands must be preceded by an OCL delimiter which has to be a line or page end code. Thus, in order to communicate mid-line changes, it was necessary to define a new OCL delimiter which was not a page end or line end code. The present expedient is directed to such a definition.

The present expedient permits a communicating word processor to send documents having more than one pitch or type style therein.

An example of a solution to the problem follows: Define an OCL delimiter that is not a line end code. Use the existing Define OCL command and add a new sub-keyword MID that defines the mid-line OCL delimiter by the following steps: ,DEF (LE)

X MID (LE) ,END (LE) (LE)=OCL separator X=mid-line OCL delimiter.

This OCL is included as part of the initial format OCL. Its purpose is to allow the user to uniquely define the mid-line OCL delimiter and to insulate current applications from undesired detection of mid-line OCL sequences.

The mid-line OCL delimiter can be used at the start of a format change OCL sequence when a keyboard change, type style change, symbol, or any other mid- line format change is to be generated, to thereby change the active format t...
