R:BASE 7.6 for Windows Label Designer includes the option of "SuppressRepeatedValues" for Data Field objects. The default is set to False.
                              
When the value of a field (as determined by the Data Field property) is the same across several records, the SuppressRepeatedValues property allows you to print the value only once each time the field value changes. This can be useful in labels where a highly redundant field has been included in the Detail band (for example, the City field in a label containing addresses.) If the Detail band overflows onto a new page, you can force the suppressed value to print again by using the "ReprintOnSubsequent" property.

You can use the "ResetBreak" property to further control the behavior of SuppressRepeatedValues. Normally the "DB Text" object tracks the text value of the field, suppressing any repeated values. It does this without any regard to breaks which may have occurred. By associating a DB Text object with a break, you can force values to reprint whenever there is a break, regardless of whether the text value was the same for the previous record.

To set the SuppressRepeatedValues property in the Label Designer, position your mouse cursor over the DB Text object and click the right mouse button. The SuppressRepeatedValues option will be displayed in the speed menu. If it is checked, SuppressRepeatedValues is on. Selecting the SuppressRepeatedValues option from this menu will toggle its value.

The "ReprintOnSubsequent" property is used in conjunction with the "SuppressRepeatedValues" property. When SuppressRepeatedValues is set to True, and detail lines have overflowed onto a new page, you can force Data Field to reprint on the first detail line of the new page by setting ReprintOnSubsequent to True. The defaults is set to False.

To set the ReprintOnSubsequent property in the Label Designer, position your mouse cursor over the component and click the right mouse button. The ReprintOnSubsequent option will be displayed in the speed menu. If it is checked, ReprintOnSubsequent is on. Selecting the ReprintOnSubsequent option from this menu will toggle its value

The ResetBreak property is used to specify a control break for a label calculation. Each time the data value of the field specified by the Break's BreakName property changes, the calculated value of the "DB Calc" control is reset to zero, and the calculation begins again. When the ResetBreak property is NULL, it can be set by dragging the label control into a BreakHeader or a BreakFooter band. This property can also be set by accessing the calculations dialog from the speed menu for the label control.

Note: For "DB Text" objects, the ResetBreak property can be used to control the behavior of the SuppressRepeatedValues property. Normally the DB Text object tracks the text value of a field, suppressing any repeated values. It does this without any regard to breaks which may have a occurred. By associating a DB Text object with break, you can force a DB Text object to reprint when the break value changes.
