Greetings,
I wonted to insert additional 8 bit to the equipment field. I tried several attempts
without success. I have got the following error:
******************************* flight_msg_.a ******************************
1758: Departure_Time at 52 range 8 .. 71; -
-sam
A -------^
A:error: Appendix F: component must be aligned on a 4 byte boundary
1759: Cruising_Level at 60 range 8 .. 167; -
-sam
A -------^
A:error: Appendix F: component must be aligned on a 4 byte boundary
1760: Route at 80 range 8 .. 14423; -
-sam
A -------^
A:error: Appendix F: component must be aligned on a 2 byte boundary
The original record representation is in file named flight.org.txt
The modified one, which produced the above error, is in the file named flight.new.txt
Your help is highly appreciated!
Best regards,
sam
