To invoke EDIT/3000 enter in interactive mode, enter:


  EDITOR

The system responds with a message similar to the one below and displays the EDIT/3000 prompt, awaiting your commands:


  HP32201A.07.17 EDIT/3000 Mon, Mar 28, 1994, 3:19 PM
  (C) HEWLETT-PACKARD CO. 1985
  /

For example, to create a new work file, you issue the ADD command and enter data. After the data is entered you use the KEEP command to save it as a permanent file. For example:


  /ADD
      1
      .
      .
      .
    100 //
  /KEEP filename,unn

To modify an existing file, use the TEXT command to open it in EDIT/3000, make the necessary modifications, and then use the KEEP command to save it. For example:


  /TEXT FILE1
      .
      .
      .
  /KEEP FILE1
  FILE1 ALREADY EXISTS - RESPOND YES TO PURGE OLD AND KEEP NEW
  PURGE OLD? yes

Below is a summary of commands you may use with EDIT/3000.

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.
