EDIT/3000
Operation
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.
