#### Type 3000

Type 3000 files contain fixed-length, fixed-format, non-homogeneous record data. They are often used to simplify the interface between Midas and other systems that generate data for Midas analysis. In a Type 3000 file, one data element is one record. Each record contains unlimited subrecords, each associated with a name, data format, and byte or bit offset within the record. Although each record has the same length and composition, the subrecords within the record may be of different formats and they don't need to be contiguous. This lets NeXtMidas access a large variety of foreign data structures without requiring special software for each one. Records can be tagged with physical abscissa information just as with other file types. The Type 3000 header contains:

- physical abscissa units
- physical abscissa starting value
- physical abscissa increment
- number of subrecords
- bytes per record
- subrecord structure, including name, format, and offset
