HC11 LCD Display problem

Gurus,
I am a virgin and need some help here. I want to display the content of a location on the LCD Display. Please have a look at the code and help me.
With the current progra the problem is that it displays correctly the value at the first 2 postions of the display, but after these positions there is junk displayed.
Below is the relevant code. IT is for an HC11
Thanks Peter

I don't see how any of that works towards solving the first problem you mentioned. In fact it's likely to worsen it.

I take that back, the eleventh line from the end of your listing may help somewhat.

Lighten up, it was funny. Maybe.
Anyway in the third line it looks like you're only loading one byte into your message table, and never setting a stop character ($00 or $04) at all! So the first two letters which will be "FF" will display fine, but when the loop comes around to load more characters or detect a stop character, you've set nothing. Therefore the program will spit out whatever happens to be in that memory location and won't quit until it finds a $00 or $04.
At least that's my feeble, never-having-used-an-HC11-myself opinion.
Hope that helps.
(hee hee, don't forget to strip that upper, uh, "nibble")
