Abstract

PURPOSE:To omit the operation of a cursor movement and to improve the operability by constituting the processor so that a repeat function of a block unit of a character-string can be realized. CONSTITUTION:When an input from a keyboard KB is supplied, an interrupting signal is sent to a microprocessor CPU, various control signals stored in a ROM are read out, and various controls are executed. In such a state, when row/column positions of an origin and an end point of a block are determined, row width/column width of the block are derived by a row width/column width arithmetic means, and by operating a block repeat instructing means, a cursor position is allowed to jump by a cursor moving means by row width or column width of the block, and document data corresponding to the row and the column of its cursor position is transferred by a block portion. In such a way, data of a document store means subjected to block repeat processing is converted to display data, and thereafter, displayed by a display means, and the operation is simplified.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a character processing device having a document editing function such as creation/editing of a text, and particularly to an operation in copying block units of character strings constituting a text. The present invention relates to a character processing device aimed at improving character performance.

[Prior Art] For example, when copying a character string block by block in a character processing device, first specify the copy range, then move the cursor to the copy destination, and then start the copy function. By doing so, the target block was copied.

Also, similar to copying, there is a repeat function for each character. By moving the cursor to a character to be repeated and activating the repeat function, the cursor was moved and one character was copied at the same time.

[Problem to be solved by the invention] However, in the above method, a specific block is copied to the next line of the block (functionally, it is repeated)
When doing so, you must specify the range of a specific block, move the cursor to the next line of the block, and then start the copy function. The present invention aims to simplify the operation by omitting the operation of moving the cursor in the above procedure by enabling repeating in units of blocks.

[Means for Solving the Problems (and Effects)] According to the present invention, when specifying a block range, the block range specifying means is operated to select the document data in the document storage means corresponding to the specified line column. The address is converted by the address conversion means, and by repeating this procedure twice, the start and end points of the block are known. Once the line column positions of the starting point and end point of the block are determined, the line width/column width of the block is determined by the line width/column width calculation means.

Next, when the block repeat instruction means is operated, the cursor position is jumped by the cursor moving means by the line width or column width of the block. The address of the document data corresponding to the line column at the cursor position is determined by the address converting means, and the document data is transferred from the determined document data address to the address in blocks.

The data in the document storage means that has been subjected to the block repeat processing in this manner is converted into display data and then displayed by the display means.

[Example] Hereinafter, the present invention will be described in detail with reference to the drawings.

The DISK stores documents created in a memory for storing standard documents, and the stored documents can be called up when necessary by instructions from the keyboard.

CR is a cursor register. The CPU can read and write the contents of the cursor register. A CRT controller CRTC, which will be described later, displays a cursor at a position on the display device CRT corresponding to the address stored here.

DBUF is a display buffer memory that stores patterns such as document information stored in TBUF.

MDBLIF is a buffer memory for displaying messages.
Stores message data patterns in OM.

CRTC is cursor register CR and buffer DBUF
