what does this do ?

[ishare]

here are a portion of  build-in asm code  :

    "  .long 661b\n"                    \
    "  .long 663f\n"            \
    "  .byte %c0\n"             /               \
    "  .byte 662b-661b\n"                       \
    "  .byte 664f-663f\n"

what is 661b ,663f ? etc . 
what do they  mean?

thanks!

Apprently here, 661b is an hex value.
You code is a bit strange because it is probably from C source that
generate asm code at runtime
But outside of the context it has non sense for me.. %c at the foutrh
line should be for string formating of a c program... and in theory if
we want to use hex value we use a "0x" prefix to avoid
misundertanding.
Do you have a link to the originall source or the project which this
code come from?
