This, a lot of time, can be rilevant, also for a small 10F.

Pay attention to this: YOU think that is irrelevant! But You are asking us =
to
find a relevant problem in the code before and after. Never do this unless =
you
KNOW what are you doing.
In this case the instruction are VERY RELEVANT because are inside a main lo=
op
and each instruction can be "long" 1 or 2 us so the code that we can not se=
e can
be of 6 to 12 us!

You are naming a variable with a name very close to PIC internal register,
personally dont like it because e small typo can lead to subtle error!

NEVER do this! Ever use labels with gotos.
This kind of use is only for rare occasions, dont waste ;-)

Waiting for the entire code... I remember you that with the Simulator of MP=
Lab 8
you can simulate ad measure accurately this code.
