>My forms use the (default) Arial font for label controls. I would like a "degree symbol" in a label control, but (whoa is me) don't know how. Any help from my esteemed colleagues appreciated.

Do you mean this ° symbol? If so, you can grab a copy from the Character Map tool (if installed) or use your keyboard. Press and hold the Alt key and press 0176 on the numeric keypad. Release the Alt key. Voila.
