Fuel oil and kerosene sales [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.
Compressed file:
The DOS self extracting file was executed on a Windows PC. The decompressed
DOS ASCII files were transferred to a UNIX server in binary format and retain
their original time and date stamps.
Processed documentation file and report:
The original DOS ASCII documentation and report were 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 015) were removed with UNIX "tr". The "fixed" documentation and
report files were saved with .TXT file extensions.
Processed data table and file:
The DOS ASCII data table TABLES91.TXT was examined with Perl "cio" to
identify extraneous control and high ASCII characters. Form feeds (octal 14)
and octal 257 were replaced with a blank using Perl "fix". DOS carriage
return characters (octal 15) were removed with UNIX "tr". The "fixed" table
was saved with the standard .TXT file extension.

"cio" output for the original ASCII diskette files.
The non-delimited fixed ASCII data file DATA91.TXT was translated to ASCII
comma separated value (ASCII CSV) data file format with Windows DBMS/COPY
according to the specifications in the User's Guide. Variable labels were
added to the output file. The DBMS/COPY translation log was checked for data
translation error messages. The first and last five records of the output
file were checked for data value translation accuracy. The DBMS/COPY input and
output data dictionaries follow:
