Formal metadata: information and software
tcldbf is an extension of Tcl/Tk that provides the Tcl script writer some ability to read and write DBF files. Its core is a set of C wrappers that read dBase files using Frank Warmerdam's shapelib and make the results available to Tcl procedures.

You'll need Tcl/Tk installed on your system in order to make use of this software. You can download Tcl/Tk from ActiveState, the company that currently provides an excellent free distribution:
<http://www.activestate.com/Products/ActiveTcl/>Assuming you're using Microsoft Windows and you installed ActiveTcl into
C:/Tcl
, copy the DLL file (at this writing
dbf1.2.dll
) into the directory C:/Tcl/lib
.
Then create a directory C:/Tcl/lib/dbf
, copy the file
pkgIndex.tcl-win
into it, and rename the file
pkgIndex.tcl
. To test, open a command prompt window,
type tclsh
, then at the %
prompt, type
package require dbf
. The response should be the
version number of Tcldbf, at this writing 1.2
.
