That should be fixed now in CVS. Do "cvs update" and make. This should  
make the typesizes.mod file in include/$HOSTTYPE
But if you don't have typesizes.mod on your system already, you don't  
have a netCDF version compiled with Fortran90 (which you will need in  
the future).

This should do the same:
bash: rads2asc sat=tx cycle=100 pass=25 -r0 sel=26 lim:26=0,0 out=-  
2>&1 |less
and I DO get the flag bits. Also my stats are different:

Maybe you have an error in the getraw.nml file you made?
