Yes I'm sure of it ,I have  a RS 232 -Hyper Terminal Connection to view the
line.And sometimes it re starts. At first I thought it was a compiler error
,probably caused by floating point library .but when I checked the MCLR pin
with scope i saw cripples.so decided to put a capacitor.
It almost fixed the line but still i'm not sure that if i can get better
results .

Are you sure it's resetting because of an MCLR reset? Could it be a
brownout reset, or something like that? How do you know the chip is
resetting at all?
