I received a few messages pointing out that the click this program produces is hardly audible on fast computers. I knew this was going to be a problem, but I don't know enough assembler to devise a clockspeed-independent delay routine. For those who do not have an assembler, you could try to patch the binary CLICK.COM (e.g. using debug); the word (2 bytes) at offset 3Fh determines the duration and therefore the volume of the click. It may be better to search for the byte sequence B9 28 00, and change the 28 00 into something that works better for you (I'm not entirely sure about the 3Fh offset). I only have an 8 MHz 8088, so I never had a need to make the program speed independent. Anyone who can is encouraged to do so (please send me a copy, or better yet, post it). Good luck.
