Hi,
I'm trying to use Peter Anderson's LCD_CTRL.ASM code (originally for
16C84) on my 16F84.  I get the following error message and can't figure
out why?  I suspect it may have to do with the difference in the memory
layout between chips???  How can I fix this.  Thanks in advance.

"Message[302] D:\LCD_CTRL.ASM 182 : Register in operand not in bank 0.
Ensure that bank bits are correct."
