This code help user to concatenate two string.
The node automatically insert a space between "string1" and "string2".
If you don't want the space between the two string you just have to declare a variable msg.setconcat variable and set the value to "1", otherwise enter "with space" or "without space" in the menu; thanks to this it will be possible to concatenate the two strings without space.
- Use msg.string1 as the first variable.
- Use msg.string2 as the second variable.
WARNING: The variables "string1" and "string2" need to be insert in order.
