splitting a long token across lines

[Nakamura]

Hi all,

Say, I have a very long integer constant , how can
I split across lines ?
I tried something like
MODULUS = 7567567567567567567567567567567\
          7567507546546986094860986094860\
          2345646986598695869548498698989\
          ...
but it doesn't compile.
Is there another way to write a long numeric constant besides writing
it as a string and then converting to long? I also wouldn't like to put
it all on one very long line.

Thanks!
