What is an editor

An editor is a software program, which generally refers to writing software used to modify computer files, but some people also call PE2, HE4 (Hanshu)... and other document software editors. Common editors include text editors, web page editors, source program editors, image editors, sound editors and video editors, etc.

A program editor refers to a software program used to edit programs. It can display the source program stored in the computer on the screen, and then perform operations such as adding, deleting, replacing, and connecting as needed.

Users use this program to add, delete, modify, cut and paste files stored in the computer. Adding refers to inserting several rows of records into the old document, or adding several characters to a row of records. For example, insert several statements into the FORTRAN source program line. Deletion refers to deleting several lines of records in the old document, or deleting several characters in the records. Modification is to change certain characters in the records in the old volume to other characters. Cutting and pasting means cutting out large paragraphs from some documents and inserting them into another document to form a new document. Some editing programs also have the ability to create source files and enter file records. Depending on the user environment, editing programs can be divided into two categories. The first type is an interactive editing program, in which users provide editing instructions to the editing program through terminal editing commands. The second type is a batch editing program. The user uses editing macros to construct an editing file, and provides editing instructions to the editing program through the editing file. Depending on the content of the edited volume, editing procedures can also be divided into two categories. The first type is a text editing program, and the content of the edited volume is the text. Text generally refers to the character and text representation of objects such as manuscripts, programs, and structured block diagrams. The second category is a graphics editing program, and the content of the edited document is graphic information. After adopting multi-window editing technology, the editing program can divide a display screen into several disjoint or intersecting areas. For example, various editing states such as text, block diagrams, commands, graphics, etc. can be allocated to operate concurrently in these areas.
