#!F-adobe-helvetica-medium-r-normal--18* #!N #!CDarkGreen #!N #!Rall639 Data Section #!N #!EC #!N #!N The data section is used for Array data when either an offset in the current file or in a separate file is specified in the Array Object definition. All other Objects, including Array Objects whose definitions use the #!F-adobe-times-bold-r-normal--18* 'data follows' #!EF specification, are self-contained; their definitions include all necessary information. These Objects do not use a data section. #!N #!N The Data Explorer file format is flexible enough to describe many existing data formats without having to reformat the data. It allows you to specify byte order, which index varies fastest, whether the data type is floating point or byte, and whether the file format is binary or ASCII. #!N #!N For data that is not in a format accepted by the Data Explorer native file format, you can either reformat the data so it is acceptable, or import the data using a general importer specification (see #!Lgai,dxall110 h General Array Importer #!EL in IBM Visualization Data Explorer QuickStart Guide). #!N #!N The data section consists of a set of data items specified as text or binary by the #!F-adobe-times-bold-r-normal--18* data #!EF clauses in the various Array Object definitions. Text and binary can be mixed in the same data section, because the #!F-adobe-times-bold-r-normal--18* data #!EF clauses specify portions of the data section by byte offsets. Binary representations can be in most-significant-byte-first ( #!F-adobe-times-bold-r-normal--18* msb #!EF ) or least-significant-byte-first ( #!F-adobe-times-bold-r-normal--18* lsb #!EF ) format, as specified by the relevant #!F-adobe-times-bold-r-normal--18* data #!EF or #!F-adobe-times-bold-r-normal--18* 'data mode' #!EF clause. Binary floating-point numbers currently must be in IEEE format. #!N #!N If a Data Explorer file does not begin with a valid header (at least an #!F-adobe-times-bold-r-normal--18* end #!EF clause), it is assumed not to have a header section. #!N #!N #!N #!F-adobe-times-medium-i-normal--18* Next Topic #!EF #!N #!N #!Lobj,dxall641 h Objects #!EL #!N #!F-adobe-times-medium-i-normal--18* #!N
