Turn off date stamp, turn on zoom

OK. I'm a total newbie. I have searched through the manual, and I can't figure out how to do these two simple things. I'm sure you more experienced users know how to do these pretty easily, but for the life of me I can't figure it out. I have a Canon ELPH SD 770 IS. I must have reset something and now:

1) the date is printed on al my shots. How do I turn this fricking feature off! It's ugly!!

2) my camera used to zoom really tightly, now it only zooms about half as much before it won't go any farther.

Thanks!!!

Date Stamp - Page 66 of your manual. Shoot in any image setting but Date Stamp mode. Personally, I can think of no reason to shoot in any other setting but Large Superfine. Memory's cheap. You paid for a 10 MP camera, why use it as if it was a 2 MP camera?

Zoom - sounds like you turned off Digital Zoom (p. 58). Personally, I'd leave it off. All it does is throw away pixels you've (see above) paid for. It uses the center of the sensor instead of the whole sensor. If you're only shooting in DateStamp mode, you won't notice much difference, since you're already throwing away pixels. But if you shoot in Large, where you use all 10 MP, instead of lumping 5 pixels into every one for the photo which DateStamp does, as you zoom, the camera has to split each real pixel on the sensor into more than one pixel in the photo. So you lose sharpness and detail.

I think most powershot menus are pretty similar. In the future if things get messed up.. Simply press the menu button and under the tool tab (has a wrench and hammer) scroll down till you see 'reset all'... That will bring you back to the default settings.
