My LCD is digikey part 73-1012-ND, Optrex DMC-16117A, 16x1 char.
Please note: It acts more like a 8x2 display. Chars 9-16 begin at location 40.

This LCD needs only +5V. For contrast, I used a 10K pot, with +5V on one end,
and GND on the other end. The wiper (middle) goes to pin 3 of the LCD.

I have lots of pins on the PIC16F876, so I waste 6 of them on this LCD interface.
I operate the LCD in the 4 bit (nibble) mode. If I decide later on that I need
some of those pins back, I will try the shift register approach that many other
folks are using to save pins.
