Below are technical specifications and programming information for the H77G data file. Users are strongly encouraged to read the documentation file provided in this release for additional information on the content of this file.
H77GDAT: This file contains the H77G data in ASCII format. It contains 154,853 records with 74 variables. This file has a logical record length of 270 with an additional 2-byte carriage return/line feed at the end of each record. The content of this file is described in the file H77GDOC.PDF.
H77GSSP: This file contains the H77G data in SAS Transport format. See the H77GSU.TXT file for information applicable to SAS users of the H77G data.
Note: For users' convenience, both of these data files (i.e., the ASCII data files and the SAS Transport data files) are provided in two compressed formats: 1) a compressed ZIP file and 2) a self-extracting executable file. See Notes on Viewing and Downloading Files for information on uncompressing
