How much utility did IBM provide with 128K of memory. Where's the C compiler on the MS/PC DOS distribution disk. If all products were judged on the long term utility of their first release, then where would M'soft, IBM, et al. be now? Besides, if I was faced with trying to get on an overloaded university computer to write my 50 line lab assignment, I might find Coherent to be just the thing for me. As it happens, I'm not, so I probably won't. >* Mark Williams comes along and gives you a compiler in the deal, and all you >* can do is bitch! > >Come on .... it`s a toy. So was 128K IBM PC, by todays standards. The bitching that I hear relates to three things: no large memory model, no paging, and no swapping. For $99 you expected more than a toy? From what I've heard, for $99 you get quite a lot. Let's see, DOS 4.01 -- $85, Turbo/Quick C, $75-95. Windows 3.0, (for multi-tasking) I don't know what it really is, but let's say it's $75. Getting pretty close to $300. Or you could go the OS-2 route: $350 + M'soft Optimizing Compiler -- $350; over $700. How about any of the full blown system V system. My copy of ESIX cost $800. If I were to even consider Coherent (and I have considered buying it) would I expect the same level of features for $99 as I would for $800? No, I don't think so! Maybe that's why I paid $800 for ESIX? >* Take your snivel rags home and give it a rest will'ya. If you don't want >* it, then shut up. Keep using DOS, see if I care! > >Shut-up! Hmmmm ....

That's the beauty of >a free country :-) OK, I think we've communicated to the world that Coherent doesn't have a large memory model, doesn't page, and doesn't swap. I've posted news about products that I thought were a) a rip-off, and b) a poor value too. But now I'm tired of pressing 'n' on twenty or thirty articles because some other dis-satisfied customers just found out it doesn't have a large memory model. kaleb@thyme.jpl.nasa.gov Jet Propeller Labs Kaleb Keithley "So that's what an invisible barrier looks like"
