Hello there.

Sharul Nizam has a good example of operating the HD44780 LCD. Here is his page about the example : http://shahrulnizam.com/pic-lesson-lcd-hd44780/ :D

You can translate the code inside back into assembly - it is pretty straight forward. About displaying the sentences in assembly, you might need to use the indirect addressing mode.
PIC - UIC00B from Cytron (replacement for my broken PICKit 2), Pickit 3, MikroC for PIC
dsPIC - MikroC for dsPIC, mikromedia board (dsPIC33)
AVR - AVR Dragon
Parallax - Prop tool

I am not sure whether the example I pointing to you will display "hello" or not, but if you are looking for assembly code for Parallel LCD display, you can refer to one of Cytron DIY project, PR3. It has the example code in Assembly Language and uses parallel LCD. More info visit: http://goo.gl/eaq27

Hope it helps you. :D
