Calls an editor that lets you edit the RDO statements you have
    issued within a terminal session. By default, Oracle Rdb uses the
    EDT editor. You can use the editor to modify your previous RDO
    statements, construct your next statement or group of statements,
    or include a file with other statements.

    Example using EDT to edit an RDO statement:

    RDO> FOR J IN JOSB PRINT J.JOB_TITLE END_FOR
    %RDO-F-RELNOTDEF, Relation JOSB is not defined in database
    RDO> EDIT

    FOR J IN JOSB PRINT J.JOB_TITLE END_FOR
    [EOB]

    If you have invoked a database, you have the necessary privileges
    to use the EDIT statement.

    If you have the VAX Text Processing Utility (VAXTPU) installed on
    your system, you can invoke VAXTPU with the EDIT statement in an
    RDO session. To use VAXTPU in an RDO session, define the logical
    name RDO$EDIT in the following way:

    $ DEFINE RDO$EDIT "TPU"

    Then, when you type EDIT in an RDO session, VAXTPU is invoked. If
    RDO$EDIT is not defined, or is defined to be something other than
    VAXTPU, then the EDT editor will be invoked when you issue the
    EDIT statement. If RDO cannot find the VAXTPU shareable image,
    EDT will be invoked. To use your personal VAXTPU section file
    with RDO EDIT, you must define the logical name TPU$SECTION to be
    your personal section file.

    You can use the editor you choose with your usual initialization
    file to modify your previous RDO statements, construct your next
    statement or group of statements, or include a file with other
    statements.

  (B)0EDIT qqqqwqqqqq>qqqqqqqwqqq>
           tqq> number qqu
           mqq> * qqqqqqqj

2.1  –  number

    The number of previous statements you want to edit. This must be
    an integer. If you specify 0, RDO calls the editor with an empty
    main editing buffer. The default is 1.

2.2  –  asterisk

    The wild card character (*). If you use the wild card, RDO
    includes in the editing buffer n previous statements, where n
    is the number specified in SET EDIT KEEP n. The default is 20
    statements.

3  –  Example

    The following sequence demonstrates the correction of a
    misspelled statement:

    1. Make a mistake:

       RDO> FOR J IN JOSB
       cont> PRINT J.JOB_TITLE END_FOR
       %RDO-F-RELNOTDEF, Relation JOSB is not defined in database
       RDO>

    2. Invoke the EDT editor:

       RDO> EDIT

    3. When in the editor, change "JOSB" to "JOBS".

    4. Exit from the editor. RDO automatically executes the contents
       of the editing buffer.
