ARKDAT Syntax: arkdat [input_file] [output_file] Arkdat processes any .mem files in the current working directory that are listed in the program's input file (if it is not specified, the input filename defaults to "arkdata.input"). This input file must list one .mem file per line, where the lines are of a form such as that generated by the command: "ls -1 *.mem >arkdat.input". The program scans each listed .mem file for its ARKIVE data and lists that data and the event time to an output file (if not specified, the filename defaults to "arkdat.output"). The ARKIVE data include the cusp_id, ark_id, tape_id, tape_file_number, and total_grm_bytes. The program also reports any missing data and processing errors. Upon completion, the program reports the grand total sum of all the .grm bytes archived for the event list.
