Functional Details

This module prints its arguments as a string.

`string` | is the value to be echoed.

A single Echo module can echo a maximum of 21 strings. In the user interface, the default number of enabled `string` tabs is two. (Tabs can be added to the module icon and removed with the appropriate `...Input Tab` options in the `Edit` pull-down menu of the VPE.)

The module can print:

- Integer, float, and string values
- Integer, float, and string lists
- 2-D and 3-D vectors.

If the input is of another type, the module will echo the object class (e.g, "Field").

In the user interface, the output of Echo appears in the Message window.
