• The STATUS Command:
    • The STATUS command is used to show details about a file
    • For Midas (Blue) files, STATUS shows information in the Blue header.

    • For other file types, STATUS shows generally useful information like:
      • The number of bytes in the file (XML or TXT files)
      • That particular file type's header information (JPEG or SHP)
      • In general, any file type whose file handler subclasses BaseFile and can be STATUSed.
        • Isn't Java great?

    • The /KEY or /K switch can be used to show the Midas keywords.
    • The /DATA= or /D=<num_elements> switch can be used to show the data in the file (by running DATALIST).
