You tell
| Quote: | If you feel that you must put a delay inside an isr, and you don't
want to see that warning message, then tell the compiler to create
a 2nd instance of the delay library by adding a 2nd #use delay()
statement as shown in bold below. That way, the isr and the
code in main() (and beyond) will each have their own separate
delay routines.

I do that.But not work.Are you have another way ?
I must put many delay inside isr and alot of function that calling from inside the isr and outside .Now I have 14 warning.All warning are "warning 216 .. interrupts disable during call to prevent re-entrancy :[...]". When I cancel isr.All warning are gone.I am not sure this warning effect to destroy my ADC port too.[subject - Can open ADC port full time ? ]
Regards

If you have lots of function and delays in the ISR then you are almost certainly not using ISRs correctly. Use ISRs for time critical functions and, if necessary, set flags that the mainline code can use to determine what action needs to e performed in the main code loop.
On the VERY rare occasion you needs delays in an ISR (I can't think of any other than chip select I/O interfacing which requires a series of one or more NOPs) then use a timer dedicated to the ISR.
