Remarks

Bounds for a report based on a data file

The bounds are used to select the records whose search key is included between the value of the lower bound (returned by ..MinValue) and the value of the upper bound (returned by ..MaxValue).

Limit for a report

..MaxValue only applies to the reports based on HFSQL data files. When creating the report, you must specify that the browse is bounded by the maximum value.

Limit for a window control

The value defined for the upper bound cannot be less than the value defined for the lower bound. The minimum value is returned by ..MinValue.
