Louis, a Jx interpreter implements extensions to the language. It supports tacit programming full-heartedly and embraces first-class verbs. There are publicly available patches for Jx extensions, as well as, a pre-built 32 bit Windows dll and Pre-built 32 and 64 bit Linux libs at
http://www.2bestsystems.com/foundation/j/jx0/index.html but it is an early version of Jx based on the J701 source. Jx has evolved (e.g., the primitives =.. and =:: were added afterwards) and J's core engine has evolved rapidly as well; it has been very difficult to catch up. ("Be careful what you wish for.") :) The current unreleased version of Jx is based on the unstable official J806 beta source and there are some relatively minor Jx glitches. We were planning to wait for the official J806 to become stable and resolve the Jx glitches but I might decide instead to release a current version, as is, soon.
