I don't think this exists, but it would be really helpful to have a string module. This module would allow an external program to read strings from the canvas. I would suggest storing them in ASCII with a 0 terminator just like a C string.
For example, a string module might have the name of the current canvas. If we used a constant handle this would easily be read by an external device when the AW Designer was not running.
Another use would be for individual calibration status or serial numbers.
