File Definitions
EDIT/3000 uses seven files: INPUT, OUTPUT, WORK, TEXT, JOIN, HOLD, and USE. Each file is described below.
INPUT Used to enter commands and text records to EDIT/3000. Generally, this file is a terminal in
interactive mode and a batch input device in batch mode. EDITIN is the formal file
designator.
OUTPUT Receives messages (and prompt characters in interactive sessions). Generally this file is a
terminal in interactive mode and a line printer in batch mode. EDITOUT is the formal file
designator.
WORK Contains the information to be modified. When a file is created and text is added, or when
an external file is copied into the EDIT/3000 subsystem for modification, the text is written
into the WORK file and all modifications are performed on it. The WORK file may be saved
under a new file name or to an existing file.
TEXT An existing ASCII file copied into the WORK file with the TEXT command.
JOIN All or a portion of an external file which is copied into the WORK file with the JOIN
command. The information can be inserted into the WORK file at any point. The contents of
the existing JOIN file are not altered by the JOIN command.
HOLD A temporary file that is generally used for holding interim information.
USE An external user file containing EDIT/3000 commands and, optionally, text records which is
called with a USE command. When a USE command is issued, all commands are read from
the USE file and any EDIT/3000 messages are sent to the OUTPUT file.
