DUMPSEGY is a character-based interactive program written in C and designed to display the header information and hexadecimal and floating point sample values of digital seismic data stored in industry-standard SEG-Y format.DUMPSEGY is started at the system command line prompt, and requires at a minimum the SEG-Y data file path and name.Up to eight display options may be included on the command line following the data file name.DUMPSEGY, invoked with no options, will display information about the SEG-Y file opened, prompt the user for the sequential trace number of the seismic data trace to be displayed, directly access that trace, and display the hexadecimal values of the samples comprising that trace.DUMPSEGY options allow: 1) displaying the SEG-Y EBCDIC header, 2) displaying the binary header, 3) displaying the individual data trace header information of the user-selected trace, 4) displaying the individual samples that comprise a trace translated from the SEG-Y format into their floating point values, 5) displaying only the file information and or header information, with no display of the individual samples, for selected data traces, 6) specifying a file to receive the output, 7) specifying a sequential range of traces to display, including an increment between sequential traces, and 8) copying portions and components of the input file in binary format allowing the construction of a new SEG-Y file from the original.If started without specifying a trace range, DUMPSEGY will prompt the user for other data traces to display until the user enters 0 to exit the program * Intel 80286 or higher processor.* DOS 3.0 or later.* A hard disk drive or CD-ROM containing the input file(s) .* A math coprocessor is NOT required, but will be used if available and is strongly recommended.Please refer to the EBCDIC Header Display section below for source code compilation information concerning that display.
