I've owned my HP12c for 15-20 years and no longer have a manual. I turned it on today and had the numbers appearing with a comma. If I put in more than 3 digits in, it begins to put periods in where I would expect to see a comma. Does anyone know how to get it back to a straight digitable format??

This is easy:

To toggle between comma and period as decimal separator,
just turn the 12C of, press_and_hold the period key (right to the zero key), press and release ON, then release the period key.

If you've had your 12c all that time--then it is a gem--probably US made. The new ones are made overseas and are very poor quality.
