Martin,

Even if your code is completely correct, this warning will still be present
at every point in the code where you use a register which isn't in bank 0.

If you want pristine code, you should carefully check each of these messages
to make sure you have the correct bank selected before using the registers,
and once you are completely sure of this, disable the warning altogether
using the directive

ERRORLEVEL -302

I think that's the best that can be done.

Andy

        No.  That is how I have it in the original source code and it
seemed a bit strange to me.  This is the first PIC code I have
actually written even though I have been on this list for about 5
years.  I have written assembly code for other processors, so this
experience is like having a chat with someone from another
English-speaking country.  It's all familiar, but the differences can
throw one for a loop, sometimes.

        Warnings are usually there for a purpose even though they may
not immediately shut down what one is doing, so I figured I had better
find out what sort of trouble I was starting.

        Sorry about reviving one of those cyclic topics again.
