OLDARRAY
,
NEWARRAY
,
SEPARATOR
The arraydeduplicate statement removes duplicate elements from an array (see Text Arrays).
Parameters
This statement has three parameters:
oldarray – is a formula that calculates the original array. Usually this is a text field or variable, but it is allowed to be any formula that produces a text result.
newarray – is the variable or field that will contain the new array. If you use a field for this parameter it must be a text field. If you want to change the array in place, use the same field or variable for both the oldarray and the newarray
separator – is the separator character or characters for the array, often a carriage return, tab or comma.
Description
The ArrayDeduplicate statement removes duplicate elements from an array. As a side effect it also sorts the array into alphabetical (A-Z) order.
The example builds an array containing a list of all the cities in Vermont where you have customers. Since you may have more than one customer in a given city, the arraydeduplicate statement removes the extras and makes sure each city is listed only once.
local Cities
select State="VT"
arrayselectedbuild Cities,cr(),Customer,City
arraydeduplicate Cities,Cities,cr()
See the arraydeduplicate( function for additional explanation and examples.
