LT macro

The LT macro is available in Unica Campaign and Unica Interact.

Syntax

data1 LT data2 data1 < data2

Parameters

data1

The numerical cell range to compare. This can be a constant value, a column, a cell range, or an expression evaluating to any of the above. For the format definition of data, see the "Macro Function Parameters" section in the chapter in this guide for your product.

data2

The number(s) to compare all values in the specified column against. This can be a constant value, a column, a cell range, or an expression evaluating to any of the above. For the format definition of data, see the "Macro Function Parameters" section in the chapter in this guide for your product.

Description

LT compares the two specified data ranges, returning a one if the values in the first data set are less than the values in the second data set or a zero otherwise. It returns a new column for each input column, each containing the corresponding column in data1 compared to the corresponding column of data2 (that is, the first column of data1 is compared to the first column of data, the second column with the second column, and so on).

If data2 is a constant, each value in data is compared to that value. If data2 is a column, the calculations are performed on a row-by-row basis. The values in data1 are compared to the first row value of data2, the second row with the second row, and so on. This row-by-row calculation produces a result for each row up to the last value of the shortest column.

Note: The LT operator can be abbreviated with a less than sign (<).

Examples


`TEMP = 3 LT 4` or `TEMP = 3 < 4` Creates a new column named `TEMP` containing the value one (since three is less than four).
`TEMP = V1 < 8` Creates a new column named `TEMP`, where each value is one if the corresponding row value of the column `V1` is less than the number eight, otherwise zero.
`TEMP = V1:V3 < 2` Creates three new columns named `TEMP`, `VX`, and `VY`. The values in the `TEMP` column are the contents of column `V1` compared to the value two, the values of the `VX` column are the contents of column `V2` compared to the value two, and the values of the `VY` column are the contents of column `V3` compared to the value two.
`TEMP = V1 < V1` Creates a new column named `TEMP` containing all zeros (since no number is less than itself).
`TEMP = V1 < V2` Creates a new column named `TEMP`, where each value is the row value of column `V1` compared to the corresponding row value of column `V2`.
`TEMP = V1[10:20] < V2` or `TEMP = V1[10:20] < V2[1:11]` Creates a new column named `TEMP`, where the first 11 cells contain the results of comparing the values in rows 10-20 of column `V1` to rows 1-11 of column `V2`. The other cells in `TEMP` are empty.
