/******************************************************************************
* $Id$
*
* Project: Shapelib
* Purpose:
* Altered "shpdump" and "dbfdump" to allow two files to be appended.
* Other Functions:
* Selecting from the DBF before the write occurs.
* Change the UNITS between Feet and Meters and Shift X,Y.
* Clip and Erase boundary. The program only passes thru the
* data once.
*
* Bill Miller North Carolina - Department of Transporation
* Feb. 1997 -- [email protected]
* There was not a lot of time to debug hidden problems;
* And the code is not very well organized or documented.
* The clip/erase function was not well tested.
* Oct. 2000 -- [email protected]
* Fixed the problem when select is using numbers
* larger than short integer. It now reads long integer.
* NOTE: DBF files created using windows NT will read as a string with
* a length of 381 characters. This is a bug in "dbfopen".
