- -   | Structure of Blue Files: There are three main parts to a Blue File: Main Header The Main Header is divided into two sections:
      Fixed | Basic information about the file (start values, deltas, units).
      | Fields common to all Blue files.
      | Three keywords (called main header keywords).
      Adjunct | Details about the file layout (varies based on file type).
      | May include system modeling information.
- - Data The binary data of the file. Extended Header Stores keywords (auxiliary information about the file). Indexing into a Blue Files: It is important to note that different Midas frameworks use different indexing systems when accessing elements of a file.
    X-Midas | Uses one-based indexing which matches VMS and Fortran standards.
    NeXtMidas | Uses zero-based indexing which matches Unix and Java/C/C++ standards.
X-Midas Users Take Note:
Prior to the release of the Blue file specification some versions of Martes created Blue files with a non-standard extended header. X-Midas has been modified to allow most of the non-standard files to be read correctly.
