16f883 config fuses problem

Unable to set the fuses properly for 16f883 in ccs ver 4.110. Is this correct format ?

Code:

#include <16f883.h>
#fuses HS, NOWDT, NOLVP, NOBROWNOUT, NOPROTECT, NOPUT
#use delay(oscillator=20M)

After compilation I see EC_IO instead of external HS oscillator...
plzz help

Code:

#include <16f883.h>
#fuses HS, NOWDT, NOLVP, NOBROWNOUT, NOPROTECT, NOPUT
#use delay(clock=20M)

The keywords 'crystal', and 'oscillator' in use delay, override the fuse selection, instead using the crystal or internal oscillator respectively.
Don't put extra spaces between the 'use' and the 'delay' on some compiler versions this will cause problems.

Best Wishes
