It is not generally a good behaviour to ignore warnings, expecially about

In effect the problem is here: you are passing a string while blit needs
a pointer to a BITMAP structure.

Probably you made confusion between ".dat" extension
of the datafile file name and .dat field of the DATAFILE structure.

I guess what you wanted was something like this:
  blit((BITMAP *)data[selecto].dat, screen, 0, 0, 0, 0, 320, 200);

without the <">s.

BTW. you shouldn't need do #define selecto in your program. If you build
the .dat file with the allegro grabber it can generate also .h files
with all the #define you need...
