Each &rst namelist in your DISANG file has to end with its own "/"
character:

  &rst iat=2304,20 r1=2.0, r2=3.0, r3=3.0, r4=4.0, rk2=25., rk3=25., /
  &rst iat=2302,17 r1=2.0, r2=3.0, r3=3.0, r4=4.0, rk2=25., rk3=25., /
  &rst iat=2299,16 r1=2.0, r2=3.0, r3=3.0, r4=4.0, rk2=25., rk3=25., /


See if that helps. Adding in LISTIN=POUT in you mdin file can often aid in
debugging (although it might not help much with this error.)

...hope this helps...dac
