Hello everybody!

I have a problem. I need to write a character to the LCD using assembler language. The following works fine:
mov a, #'R0'
and the LCD displays 'R0'

But I want to print the value that is contained in the variable or register, like:
mov R0, #07
and sending 7 to the LCD.
This doesn't work, i.e. the character 7 is not printed properly. Does anyone have an idea what is the problem and how can I solve it?

Thanks in advance,
Raphael
