Below are technical specifications and programming information
for the H49 data file. Users are strongly encouraged to read the
documentation file provided in this release for additional
information on the content of this file.
H49.DAT: This file contains the H49 data
in ASCII format. It contains 23,804 records with 164 variables.
This file has a logical record length of 504 with an additional
2-byte carriage return/line feed at the end of each record.
H49.SSP: This file contains the H49 data
in SAS Transport format. See the H49SU.TXT file for information
applicable to SAS users of the H49 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 the related link for
information on uncompressing these files.
H49SU.TXT: This ASCII file contains
information for SAS users of the H49 data. This includes
information on the SAS Transport version of the H49 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.
H49CB.PDF: This PDF file contains the
codebook for the H49 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. |
