Mark,
I have used BASCOM with great success when dealing with LCD's! Sounds
like you missed something when setting up the stuff. Try to modify the
sample file for LCD i.e. lcd4.bas!

The simulator is pretty nifty, and do test the code there first! Once
you have the LCD working in simulator mode, remove the $sim switch and
compile the code again (very easy to forget) and if you have it wired
ok, it will work..... or should work!

You might find good help at the BASCOM forum (http://www.mcselec.com),
ppl here seems more into C and assembler.

Cheers
Lasse

fix, that looks like the best at this point.  If that doesn't work,
I'll try the signal injector.  Thanks again, and have a great day.

using Bascom to program and I've used the Config LCDPIN statement to
set up how the LCD is connected, but I get the dark line stuff right
from the start, even before I programmed the chip, so I suspect
there's something else afoot here.  GND is connected, VCC is 5v, 
contrast runs to a 2.2K to GND.  Pin 5 to GND.
