Has anybody else unpacked this demo | kit recently? I just unpacked this demo for friends last nite! I don't have an STe or MegaSTe, but I got 4 Mb and they were needed. First off, I received only_ste.lzh through the News at work. Unfortunately, only_ste.lzh is incompatible with MS-DOS compatible floppy disks, since they're limited to 720 Kb. As a reminder, only_ste.lzh is 802661 bytes long. What to do? I used "split" on my SPARC to chop the file in half. Each half was put on a separate floppy and taken home. At home, I became worried about concatenating two binary file parts together. I then decided to run full blown GNU emacs (not mg, jove, nor micro-emacs) with a 1 Mb RAM disk. I then inserted into my emacs buffer both halfs of the file and saved it to the RAM disk. Of course there was no more room to unpack the file. It tested out okay. Well, I copied it to a floppy and extracted back to the RAM disk. I then ran MSA to create the demo floppy. Ouffhh!!! ;-| The first thing I did then was to run VKILLER on it. It stated that the floppy was executable, but no known virus was found!! 8-) Did anyone have a much easier time of it? I only hope that few items of this sort travel through USENET or are uploaded to atari.archive. Normally, large *.lzh or *.zoo can be split up differently since the individual member files are less than 720 Kb. -- Ralph P.

Ouffhh!!! ;-| The exact procedure I followed was to run lharc on Unix (a DECstation 5000 unpacks LZH archives a *little* faster than an ST :-), split the file in two, and then wrote the floppies. On the ST the easiest way I found to do this was to `cat' the two parts (using GNU cat from cs.uni-sb.de), a lot faster than creating a RAMdisk and using GNU Emacs, I'd say... > Did anyone have a much easier time of it?

The thing might be to have a simple stand-alone SPLIT/JOIN program on the ST. If I knew more about GEM I'd do it myself (maybe I'll give it a try someday). By "simple" I mean one that does NOTHING but the equivalent of Unix's split and cat, ie. no headers or CRC's. Anyway, regarding the only_ste demo, I must confess it's absolutely fabulous. -- -- Salvador Pinto Abreu spa@fct.unl.pt Universidade Nova de Lisboa, PORTUGAL
