Abstract: A document processing system for actively processing a document targeted for one system on another system. The system of processing a document having associated field definitions targeted for a system operating in a first encoding scheme in a text editor operating in a second encoding scheme includes determining if a change to the document in the second encoding scheme violates one of the field definitions associated with the document and providing an indication to the text editor when a field definition violation is determined. The processing functions include creating, inserting, editing, deleting and formatting. The document processing system can be used when editing RPG documents in a Unicode editor for ultimate processing by a non-Unicode system such as EBCDIC DBCS. The indications can include setting a flag, which can be used by the text editor to drive visual indicators of violations, deny changes and the like.

Abstract: A method for synchronizing the contents of a line-oriented text document and a stream-oriented text document. The line-oriented text document has a sequence number area. The line-oriented text document listens for a change in the content of the stream-oriented text document and vice versa. When a change is detected in one document, listening in the other document is suspended and a complementary document change is implemented in the other document. Document adjustments resulting from such a complementary change are listened for separately, and echoed similarly into the original document.

Abstract: An extension of any n-file compare and/or merge utility in an edit system includes services provided by a parser attached to the edit system for the particular file type. A compare command in the edit system is enabled by an extension-registration process to query, upon activation, for any compare extensions supported by the parser. Selected files are displayed to a user with non-comparing elements highlighted according to a compare strategy selected with reference to the compare extensions.

Abstract: A method, system, and apparatus for intelligent document saving. An intelligent document saving method can include cropping a document to frame a changed portion of the document and saving only content framed by the cropping. Notably, the cropping step can include maintaining watermarks in the document to demarcate unchanged portions from both the start and the end of the document and, consequently, a starting and ending position in the document of the changed portion. The position of the watermarks can be repeatedly updated whenever changes are performed to the document.

Abstract: An activemark mechanism for a live parsing editor allows marks (labels) in text to be referenced or linked to any editor command, macro, or any external tool activated by the editor. The activemark mechanism includes a parsing mechanism which creates an activemark automatically when the document is loaded in the editor, and thereafter as a user enters information into the document by parsing the changes to the document as they are committed. The activemarks are dynamic in that their meaning and behavior are updated in the context of any external tool which is activated by the editor.

Abstract: Present edit systems having undo/redo functions are typically inflexible and do not permit users of computer systems to make use of these functions to the greatest advantage. The disclosed edit system having an enhanced undo interface, permits the selective display of undo elements intermixed in the edit view of the document with actual text elements and positioned relative to the affected text The user may select any undo element and selectively restore changes to the text. A series of user interface enhancements provide the user with a flexible set of capabilities for manipulating and assessing changes to a document.

Abstract: A method and editor for editing a line of text comprising mixed single-byte character set (SBCS) and double-byte character set (DBCS) text while maintaining the columnar integrity of the text after the edit point. The method and editor provide an extended cursor to indicate to the user the text which will be affected by the editing operation. The method and editor are operable on computer systems which require Shift Out (SO)-Shift In (SI) control characters, on systems which support emulated SO-SI control characters and on systems which do not.
