Below are technical specifications and programming information for the H51A data file. Users are strongly encouraged to read the documentation file provided in this release for additional information on the content of this file.
H51A.DAT: This file contains the H51A data in ASCII format. It contains 182677 records with 52 variables. This file has a logical record length of 487 with an additional 2-byte carriage return/line feed at the end of each record.
H51A.SSP: This file contains the H51A data in SAS Transport format. See the H51ASU.TXT file for information applicable to SAS users of the H51A 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
these files.

This includes information on the SAS Transport version of the H51A data, as well as SAS statements for converting the ASCII data file into a SAS data set (in lieu of using the SAS Transport file) and for creating and using SAS formats. This file also includes helpful information for inexperienced SAS users, such as sample SAS program code.
H51ACB.PDF: This PDF file contains the codebook for the H51A data file. It indicates the record layout (i.e., the start and end position of each variable) of the file. The codebook also includes listings of the variables in both alphabetical and position order, as well as the following information for each variable: 8 character name, 40 character description, format (length), type (character or numeric), start and end positions, and unweighted and weighted frequencies.
