1. While trying to learn how to define a moderately complex adverb, I have several times received a 409 error, telling me that my server is not responding. After some experimentation, with restarts, I have found a short sequence which leads to the crash:
J Http Server JVERSION Engine: j701/2011-01-10/11:25 Library: 7.01.040 Platform: Darwin 32 Installer: j701a_mac_intel.dmg InstallPath: /Applications/j701 13!:0 ] 1 negx=: 1 : '(- x) u y' 3+negx 7 |domain error: negx |negx[:0] negx=: (3 : 'u - y') : (4 : '(- x) u y') 3+negx 7 The second definition entry should have reported a Stack Error. When Debug is off, the second usage attempt reports a Value Error for u, without killing the server. 2. I see that my copy of the software is over a year old. It is not easy to find release dates on the Downloads site; additional columns for engine and library dates would be most useful. If this problem has been fixed, I would be happy to update. 3. Dictionary sections on Monad-Dyad use are terribly brief. Discussions of adverb and conjunction definition processes are longer in JLearn and JfC, and somewhat complement each other, but still leave me somewhat confused. Are there yet other elaborations available? Thanks. --ArtAnger ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
