Here's the problem:
The F77 code:
open(unit=51,name='test1.dat',status='unknown',form='unforma tted')
write(51)1,2,3
close(51)
end

The idl code(that doesn't work):

openr,n,'test1.dat',/get_lun,/f77_unformatted
x=0 & y=0 & z=0
readu,n,x,y,z
print,x,y,z -----> 1 0 2
free_lun,n
end

Code that does:
openr,n,'test1.dat',/get_lun,/f77_unformatted
x=0 & y=0 & z=0 & dum1=0 & dum2=0
readu,n,x,dum1,y,dum2,z
print,x,dum1,y,dum2,z -----> 1 0 2 0 3
free_lun,n
end

is idl not interpreting the input correctly? or.. ? ?
