I've been looking at the source code for compress.c, as I wanted to write
a 68000 TOS version of it. However, in the source it mentions that the compress
algorithm comes from an article by T. Welch in the June 1984 edition of the
IEEE transactions on computers. I looked in this edition at our library and
could find no mention of it.
Does anyone know where I can get hold of this algorithm.
Thanks in advance.

There is a working PD compress.ttp in binary form. I can send it to you if you send me a disk and appropriate International Reply Coupons (or money to cover postage). It's to expensive to send over the net. \\ .
