Probing into the great beyond

I was sitting here trying to learn all the system variable options that exist, and found out that just issuing a 'probe system' is a bad thing and hangs the system. Is this expected behavior? I tend to worry when I can lock things up that easily. --- G. Edw. Learned - [learned--talentsinc--net] (Never apply a Star Trek Solution to a Babylon Five Problem)

The latest versions of Rebol/View and Rebol/Core correctly handle this. Perhaps you should download them again? Andrew Martin ICQ: 26227169 http://zen.scripterz.org

Hi, I think this is a bug of 'mold command in Rebol/View. In Rebol/Core 2.5 probe system works without problems... Cyphre

I'm running 1.2.1.3.1 of view, which I downloaded just a couple of days ago. I do have the problem there. On core I'm on 2.5.0.3.1 and you are correct, it is handled correctly there. --On Friday, September 28, 2001 4:14 AM +1200 Andrew Martin <[Al--Bri--xtra--co--nz]> wrote:

it does not 'hang' the system. It just takes a minute to process the command. How long it takes will depend on your Processor speed, my PIII 600 with 256MB RAM takes between 15-30 seconds. I haven't timed it, that is just a guess. Enjoy!! Ammon

I think it's a problem with self references inside system and how probe works, or worked, as it apparently is fixed now. --Gregg

No: that one really does hang my system [Rebol System not the OS] :-( - Jason

Yes! Thank you :-) words: probe first system foreach word words [print word] :Jason

The problem exists only if you have View show the desktop first. If you don't then it works fine. Instead of using a combination of probe and echo to save it. You can also use just go .. save %system.txt system I think /Core veterans may agree with me here? IMHO If you develop in REBOL/View you will find things a lot easier (for iteractive testing, word lookups, help, quick calculations), if you don't have the desktop load on startup. For End Users yes, but developers no. Cheers, Allen K

don't then it works fine. Ahhhh! So that's why I thought it was fixed! (Until I tried showing the desktop first then typed in probe system in the console). Thanks for letting us know, Allen. Andrew Martin ICQ: 26227169 http://zen.scripterz.org

Agreed here, I have multiple REBOL setups, Core, View with desktop, View without. I must admit that I use the view without desktop the most. HTH! ;) Ammon
