Here's a uuencoded, compressed tar file: btree-mem.tar.Z
Changes

Win95/NT:

use WinZip to extract

(make sure name ends in ".tar.Z" -- use save as or rename if necessary)

UNIX:

uncompress btree-mem.tar.Z

tar xvf btree-mem.tar

Then there are two directories

btree-mem-C for the C++ code

btree-mem-long for the C code that just does longs

Makefiles were just changed to work on Sun w/ gcc/g++

The executables:

test_btree : shows statistics of inserting random entries with different number of max nodes in a B-Tree

demo_btree : lets you interactively modify and display a B-Tree

random : random number generator that created random.data

Let me know how it works for you.

Thanks.

p.s. Here's the README to my on-going B-Tree project.
