Add the example script to your app and run it. Then add, at least, the fields listed in the results column to a sheet in your app to see the result. RangeTab3: LOAD recno() as RangeID, RangeMode(Field1,Field2,Field3) as MyRangeMode INLINE [ Field1, Field2, Field3 10,5,6 2,3,7 8,2,8 18,11,9 5,5,9 9,4,2 ]; |

Example with expression:
RangeMode (Above(MyField,0,3))
Returns the most commonly occurring value in the three results of MyField evaluated 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 RangeMode() function.
Data used in example:
RangeTab:
LOAD * INLINE [
MyField
10
2
8
18
5
9
] ;
| MyField | RangeMode(Above(MyField,0,3)) |
|---|---|
| 10 | Returns 10 because there are no rows above so the single value is the most commonly occurring. |
| 2 | - |
| 8 | - |
| 18 | - |
| 5 | - |
| 9 | - |
