yikes, bytes, bits, structures, and splitting oh my. That certainly
works but... yikes

This can be done with a cleaver call to format and a type conversion
that is (in my opinion) the best and fastest way. Play with the type
conversion as you want I didn't include it here.

lines=file_lines('test.dat')
dat = strarr(3, lines)
openr, lun, 'test.dat', /get_lun
readf, lun, dat, format = '(a4,a16,a)'
free_lun, lun
IDL> print, dat[0,*]
