Title:
Historical monthly energy review database, 1973-1988 [electronic resource]
Original diskette files: All diskettes were mounted on a 5 1/4" drive of
a Windows 98 PC and the diskette files were copied to the PC hard drive. To
preserve the original file content, all files were transferred to a UNIX server
in binary format and retain their original time and date stamps.
Processed documentation file: The original DOS ASCII documentation was
examined with Perl "cio" (check-it-out) to identify extraneous control and
high ASCII characters. Form feeds (octal 14) and the substitute control code
(octal 32) were replaced with a blank using Perl "fix". DOS carriage return
characters (octal 15) were removed with UNIX "tr". The ASCII "fixed" file was
saved with a .TXT file extension.
Processed table and data files: The original DOS ASCII file TABLEMSN.TXT was
examined with Perl "cio" (check-it-out) to identify extraneous control and
high ASCII characters. Form feeds (octal 14) and the substitute control
code (octal 32) were replaced with a blank using Perl "fix". DOS carriage return
characters (octal 15) were removed with UNIX "tr". The "fixed" file was saved
with a .TXT file extension.
All other DOS ASCII CSV data files were examined with Perl "cio"
(check-it-out) to identify extraneous control and DOS ASCII characters. The
substitute control character (octal 32) was replaced with a blank using
Perl "fix". DOS carriage return characters (octal 15) were removed with
UNIX "tr".The "fixed" ASCII CSV files were saved with .CSV file extensions.
You can view the 1991 "cio" output for the
original ASCII diskette files.
