J has some globals in the "j" namespace it uses for locating items and for providing shortcuts for loading them. In J7, these are SystemFolders_j_, UserFolders_j_ and Public_j_.
These are all two-column "name-value" pairs. For example, my SystemFolders has an entry like 'addons';'C:/Program Files/J701/addons' which tells J where to look when I do something like " load '~addons/graphics/viewmat/viewmat.ijs' ". Also, Public_j_ has an entry like 'viewmat';'~addons/graphics/viewmat/viewmat.ijs' so I can simply enter " load 'viewmat' ". UserFolders is just like SystemFolders but it has your own idiosyncratic folders. You can update these in the gtk interface for J7by selecting "Edit/Configure/Folders". J6 has analogs to these with the names all in upper-case (though USERFOLDERS_j_ has a third column which is some kind of flag). ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
