21 of 97    21 The program is now waiting for us to enter the card number for the first search item we wish to sort the records by.  Type the number 1 and hit  [ENTER].  The program is now waiting for us to enter the item or factor number for the first search item we wish to sort the records by.  If we refer to our Factor Table (see p.7 )  LAST UPDATE  is factor number 25 on Card One, so type the number 25 and hit [ENTER]. The program is now waiting for us to enter a BOOLEAN OPERATOR, such as an =, <, >, or <> symbol; which represent “equal to”, “less than”, “greater than”, and “not equal to,” respectively.  Since we are looking for records modified on or after a certain date, we want records that have a date value for this field that is "Greater Than or Equal To" our cutoff date.  For our example, let’s say we want all records modified after September 1st , 2000.  Type a “greater than” symbol > immediately followed by an “equal sign” =  and then hit  [ENTER]. NOTE: DO NOT HIT ENTER BETWEEN TYPING THE TWO SYMBOLS. Your screen should now look like the one shown below. The factor whose card and item number we have specified may be compared to more than one parameter. The program always assumes that we are going to give it more than one parameter for comparison.  It is now waiting for us to indicate whether we want the specified factor to match all of the given parameters by typing the letter ”A” for “and,” or if the factor can match any one of the parameters by typing the letter “O” for “or.”  Since we are comparing to only one single value, it does not matter here whether you type “A” or “O,” so type one of them and hit  [ENTER].
