joinarray() Function


joinarray( array, separator )

Concatenates the elements of an array together into one string and inserts a string separator between each element.


Keyword Type Description


Any Type Array

An array of elements to be concatenated.



A string that will be inserted between each element of the given array.



Usage considerations

Acceptable array types

This function works with any array type, performing a string conversion on each element if necessary.

Understanding results

If no separator value is defined, then a default empty text is used.

If an array with only one element is entered as the array argument, the function will return only the element without the separator value.


joinarray(pv!processVar3, "|") returns 1|2|3|4 where pv!processVar3 is a process variable which holds the number array {1, 2, 3, 4}
