Beautiful! Thanks so much, moke123. It works! I appreciate it!My code loads the mask on the first keystroke using A, a, C, or c. The cursor then moves to the first digit position.
Any other key besides A or C fires a message box. Hitting Escape will clear the textbox and mask.
Still needs some cleanup and experimenting but works OK.

Edit: Made a few changes, one being able to tab past the textbox without issues.
