Although there has been a lot of AVL tree libraries available now, nearly all of them are meant to work in the random access memory(RAM). Some of them do provide some mechanism for dumping the whole tree into a file and loading it back to the memory in order to make data in that tree persistent. It serves well when there s just small amount of data. When the tree is somewhat bigger, the dumping/loading process could take a lengthy time and makes your mission-critical program less efficient. How about an AVL tree that can directly use the disk for data storage ? If there s something like that, we won t need to read through the whole tree in order to pick up just a little Bit imformation(a node), but read only the sectors that are neccssary for locating a certain node and the sectors in which that node lies. This is my initial motivation for writing a storage-media independent AVL Tree. However, as you step forth, you would find that it not only works fine with disks but also fine with memorys, too.

graspForth is my humble attempt at a Forth-in-C that has the following goals: GCC ......... to support all 32-Bit micros that GCC cross-compiles to. Relocatable . to be able to run in-place in either Flash or Ram. Fast ........ to be "not much" slower than an assembly based native Forth. Small ....... to fit-in approx 300 words in less than 25Kbytes on a 32-Bit machine. Portable .... to achieve a 5 minute port to a new 32Bit micro-processor, or micro-controller.

LZW壓縮和解壓縮程序 lzw.c 主要的功能模塊 Bitio.c/Bitio.h 一些支撐函數，支持以比特(Bit)為單位的文件I/O 用法： 壓縮 lzw E <in-file> <out-file> 解壓縮 lzw D <in-file> <out-file> 壓縮時，讀入<in-file>中內容，壓縮后存入<out-file>中，得到壓縮文件。 解壓縮時，讀入<in-file>中內容，將結果存入<out-file>中，得到原文件。 本代碼在linux+gcc/windows+vc下經過測試，為了使讀者容易理解算法本身， 算法實現中僅采用了簡單的錯誤處理機制和優化。
