VAXTPU MOVE_VERTICAL — VMS 5.2

 MOVE_VERTICAL

 Moves the active editing position up or down in the current buffer by the
 number of rows specified.

 Syntax

    MOVE_VERTICAL (integer)

 Parameters

    integer    The number of rows the editing position moves.  Positive
               values are down (toward the bottom of the buffer).  Negative
               values are up (toward the top of the buffer).

 Comments

 By default, VAXTPU keeps the cursor at the same offset on each line.
 However, since VAXTPU counts a tab as one character, regardless of how
 wide the tab is, the column position of the cursor may vary greatly from
 line to line even though the offset is the same.

 To keep the cursor in approximately the same column on each line, use the
 following statement:

    SET (COLUMN_MOVE_VERTICAL, ON);

 This statement directs VAXTPU to keep the cursor in the same column unless
 a tab character makes this impossible.  If a tab occupies the column
 position, VAXTPU moves the cursor to the beginning of the tab.

 Example

 The following procedure moves the current character position by eight-line
 sections and puts the cursor at the start of a line:

    PROCEDURE user_move_by_lines
       IF CURRENT_DIRECTION = FORWARD
          THEN
             MOVE_VERTICAL (+8);          ! down a section
          ELSE
             MOVE_VERTICAL( -8);          ! up a section
       ENDIF;
       MOVE_HORIZONTAL (-CURRENT_OFFSET); ! go to start of line
    ENDPROCEDURE;
