I have a binary file and I would like to get the first,second and third field of the line The first field is with offset zero (ofcourse) which has a size of 2 bytes and its format is binary integer format. The second field is offset 2 and size of 2 bytes with binary integer. The third field has offset of 4 with 2 bytes with binary integer data. I was wondering what is the easiest way to do this? I am getting confused on how to use unpack. also, lets assume one of these fields is ASCII -- Offset 15, size 1 --, how could I see this string? Any thoughts? TIA

  • All field sizes are fixed and constant.
  • All fields are contiguous. There is no explicit 'padding' between fields regardless of the data types, size and alignment issues.
  • The binary fields are provided in Big Engined Format which is unsigned
  • ASCII strings are left align, null padded
