Below are technical specifications and programming information for the H77C data file. Users are strongly encouraged to read the documentation file provided in this release for additional information on the content of this file. H77CDAT: This file contains the H77C data in ASCII format. It contains 9,671 records with 31 variables. This file has a logical record length of 221 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 H77CDOC.PDF.
H77CSSP: This file contains the H77C data in SAS Transport format. See the H77CSU.TXT file for information applicable to SAS users of the H77C 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
