Replaces placeholders, token names, alias names, or routine names
    at the current cursor position with the appropriate body of text
    or code, if the cursor is not on an overview line. Replaces an
    overview line with the underlying source lines, if the cursor is
    on an overview line. Expands symbols to include their occurrences,
    if the cursor is in a query buffer.

    Format

      EXPAND

1  –  Qualifiers

1.1    /DEPTH

       /DEPTH=n
       /DEPTH=1 (D)

    Specifies how many levels of detail are displayed. If you specify
    the value ALL, all subgroups for this overview line are expanded.

    If the cursor is not on an overview line or is in a query buffer,
    the /DEPTH qualifier is ignored.

1.2    /GOTO_PLACEHOLDER

       /GOTO_PLACEHOLDER (D)
       /NOGOTO_PLACEHOLDER

    Specifies whether or not the cursor should move to the next
    placeholder after performing the EXPAND operation. The movement
    to the next placeholder does not take place if it would force the
    current position to scroll off the screen.

    If the cursor is on an overview line, the /GOTO_PLACEHOLDER
    qualifier is ignored. Note that when you use the EXPAND command
    with SCA, this command does not support the /GOTO_PLACEHOLDER
    qualifier.
