Abstract
An earlier report (Caldwell, 1987) described the specification for a binary file format in use at DREA at the time. That report described a format that consisted of a file containing a header, with information on the file and its contents, that was followed by the file’s data. Eventually this format, familiarly know as the “DREA.DAT” format, proved to be insufficient to contain data recorded by the evolving nature of the instrumentation and the requirements of researchers. That formal became enhanced, becoming the higher resolution “DREA.DAT32” format. Over time programs were written to produce data in DREA.DAT32 format, as well as to read and use the contents of these files. However no analogue to Caldwell’s report was ever produced, which meant that user’s were essentially free to do what they wanted with the format, within limits. This report sets down the requirements and specifications of the DREA.DAT32 format based on data gathered from programs that write and read the files, as well as from users of DREA.DAT32 files and the programs that use them.
