LOAD recno() as RangeID, RangeMax(Field1,Field2,Field3) as MyRangeMax INLINE [

Field1, Field2, Field3

6 9

Example with expression:

RangeMax (Above(MyField,0,3))

Returns the maximum value in the range of three values of MyField calculated on the current row and two rows above the current row. By specifying the third argument as 3, the Above() function returns three values, where there are sufficient rows above, which are taken as input to the RangeMax() function.
