REDUCE command

The REDUCE command reduces the size of an example table, COMMENTS box, or CONDITIONS box.

To reduce without a function key:

  1. Type REDUCE on the command line.
  2. Position the cursor as is shown by one of the diagrams on this page.
  3. Press Enter.

To reduce with a function key, position the cursor in the area you want to change and press the Reduce function key. The following diagrams show this method. An asterisk indicates the position of the cursor (*).

Example 1: Remove a column. Put the cursor above the line, within the column, and press the Reduce function key. 



Before:                              After:
 
TNAME | COL1 *| COL2 | COL3 |        TNAME | COL2 | COL3 |
------+-------+------+------|        ------+------+------|
      |       |      |      |              |      |      |

Example 2: Narrow the table-name column. Put the cursor above the line, in that column, and press the Reduce function key. 



Before:                              After:
 
TNAME  * | COL1 | COL2 | COL3 |      TNAME | COL1 | COL2 | COL3 |
---------+------+------+------|      ------+------+------+------|
         |      |      |      |            |      |      |      |

Example 3: Narrow any other column. Put the cursor on or below the line, in that column, and press the Reduce function key. 



Before:                               After:
 
TNAME | COL1 | COL2      | COL3 |     TNAME | COL1 | COL2 | COL3 |
------+------+-----------+------|     ------+------+------+------|
      |      |        *  |      |           |      |      |      |

Example 4: Remove a row. Put the cursor under the table name, in the row to be removed, and press the Reduce function key. 



Before:                               After:
 
TNAME | COL1 | COL2 | COL3 |          TNAME | COL1 | COL2 | COL3 |
------+------+------+------|          ------+------+------+------|
P.    |   10 |      |      |          P.    |   10 |      |      |
P.  * |      | J48  |      |

Example 5: Narrow a CONDITIONS or COMMENTS box. Put the cursor below the line, inside the box, and press the Reduce function key. 



Before:                               After:
 
|             CONDITIONS           |  |     CONDITIONS     |
|----------------------------------|  |--------------------|
|                  *               |  |                    |

Example 6: Remove a row from a CONDITIONS or COMMENTS box. Put the cursor below the line, on the vertical bar at the left, and press the Reduce function key. 



Before:                               After:
 
|      CONDITIONS     |               |     CONDITIONS     |
|---------------------|               |--------------------|
*  _COL1 > 100        |               | _COL3/12 < 90      |
|  _COL3/12 < 90      |
