The Concatenate block joins multiple text strings into one string.

For information on using dataflow blocks, see Dataflow.

The following properties of the Concatenate block can take input and give output.

• input n (string)
• strict (boolean)

input n specifies one of the strings to concatenate. A null input is treated as empty text. Click the plus sign in the block to add more inputs.

strict specifies how null inputs are handled.

• TRUE: If any input n is null, output returns null.
• FALSE or null: Null inputs are treated as empty text.

The following property of the Concatenate block can give output but cannot take input.

• output (string)

output returns a string formed by concatenating all of the input values.

The following image demonstrates a Concatenate block. In this example, three strings are concatenated.
