[DRG]

The way I understand it is this:

The code reserved a space up to the limit ( lets say it's 25 for now ) and after that is more code probably unrelated to that previous code and that code expects to find the info it needs at that spot.....if we allow more text then NOT ONLY do we have to make sure every place that text string is used still fits in the old space available with the increased number of characters but MORE IMPORTANTLY...... now that code that comes afterward that expects to find code starting at a specific point......now finds the tail end of the expanded text string .......and then things go downhill from there.

We could try it as an experiment to see what goes wrong but sometimes what goes wrong doesn't show up right away. I have MANY times wished the unit name could be 16 characters instead of 15 so I have heard the reason why many times in the past 20 years
