You can't access them from Euphoria, because they aren't there 

These are macros, and so at compile time, wherever NCURSES_ATTR_SHIFT
is referenced, it simply becomes 8. A_COLOR becomes 0xff00 - I think


So, you'll have to just define a constant in your code, and hope the
ncurses code doesn't change 

By the way, I think it is cool that you're wrapped ncurses.  Good job!

Now that ncurses isn't really needed (what with the new version coming
that doesn't included it), we can use a better () console library
such as slang or better yet, TxWin - http://svn.netlabs.org/txwin -
works in 32-bit DOS, Windows, and Linux.  Made for Watcom too!
