contains sample Unix C-shell (csh) scripts for accessing 1990 Census data on the Internet at the University of California. These routines require a Unix computer with NFS access to the Internet. The examples can be modified to obtain data from any of the following:

	Summary Tape File 1A	18 CD-ROMs
	Summary Tape File 1C	1  CD-ROM
	Summary Tape File 3A	62 CD-ROMs
	Summary Tape File 3C	2  CD-ROMs

DBUTIL

• DBUTIL: Unix software for accessing 1990 Census data on CD-ROM (Deane Merrill)
• DBUTIL: The UNIX Interface to 1990 Census Data on CD-ROM (Nathan Parker)

The C-shell scripts make use of the Unix-based DBUTIL software package written by Nathan Parker. DBUTIL reads dBase-III DBF and NDX files on the CD-ROMs and produces formatted ASCII files, with data field descriptors, of the data selected by the user. Input and output file formats are compatible with Lawrence Berkeley Laboratory's SEEDIS (Socio-Economic Environmental Demographic Information System).
