**EqualLeftBuffer( <;**//caseflag>//** )**

{{blk2blue.jpg|blk2blue.jpg}}

| **EqualLeftBuffer** | Compares left buffer value to corresponding "buffer" field |
| //caseflag// | A BYTE value that designates that the matching value is case sensitive. A value of 1 (TRUE) makes the comparison result case sensitive. |

The **EqualLeftBuffer **method returns one (1) if each "left" field equals its corresponding "buffer" field; otherwise it returns zero (0).

**Implementation:**

The "left" field is the //first //(left) parameter of the AddPair method. The "right" field is the //second //(right) parameter of the AddPair method. The BufferedPairsClass automatically supplies the "buffer" field.

**Return Value:**     BYTE

**Example:**

** Fields.AddPair(CUST:Name,  CustQ.Name)  !establish Name pair**

** Fields.AddPair(CUST:Phone, CustQ.Phone) !establish Phone pair**

** Fields.AddPair(CUST:ZIP,  CustQ.ZIP)    !establish ZIP pair**

** !some code**

** IF ~Fields.EqualLeftBuffer         !compare CUST fields to save buffer**

**  CASE MESSAGE('Abandon Changes?',,,BUTTON:Yes+BUTTON:No)**

**  OF BUTTON:No**

**   Fields.AssignRightToLeft         !copy changes to CUST (write) buffer**

**  OF BUTTON:Yes**

**   Fields.AssignBufferToLeft        !restore original to CustQ (display) buffer**

**  END**

** END**
