Yes, I could run my apps from the IDE window, but many times it is nice to just have the app be a link on the screen. And distributed apps could be run from the IDE as well, but it is nice that the IDE doesn't pop up showing that the app is written in J. Make an app written in J look no different than any other app.
When J is installed on a system it is nice not to have complete copies of J included in each standalone app. Sure saves on disk space. Of course the down side is that apps are written for a particular version of J and may fail as happens with Java apps. In my case I am not building a super-duper complex app. One I did in J6 simply gave a directory structure reporting space used by files and subdirectories in each directory. Not much to it. No need to go through the Project Manager. Just one ijs script. But I could run it just like non-J apps. What really mystifies me is that the wd 'ide hide' prevents the IDE from appearing as long as the form is open, but then appears when the form ends. I searched all the J libraries and the IDE appearing is not done with wd 'ide show'. And in my browsing around I ran into a few things that were undocumented and couldn't figure out what they did.
