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压缩和解压缩程序 lzw.c 主要的功能模块 BItio.c/BItio.h 一些支撑函数，支持以比特(BIt)为单位的文件I/O 用法： 压缩 lzw E <in-file> <out-file> 解压缩 lzw D <in-file> <out-file> 压缩时，读入<in-file>中内容，压缩后存入<out-file>中，得到压缩文件。 解压缩时，读入<in-file>中内容，将结果存入<out-file>中，得到原文件。 本代码在linux+gcc/windows+vc下经过测试，为了使读者容易理解算法本身， 算法实现中仅采用了简单的错误处理机制和优化。
