With all due respect, and genuine appreciation for your fine work on the "J

Does there is a source (maybe .tex file) of J Referance Card for easy
modification & improving?

My question #2 had two clauses with opposite senses (i.e. it was an either/or
question), so an unqualified "no" is an ambiguous response. Let me phrase it
as a strict yes/no question:
Does x ]@(v) y necessarily produce the same result as x ]@v y ?

The multicolor page is the only version that we plan to produce. Since

Perhaps it's worthwhile to extend
http://www.jsoftware.com/jwiki/Books#J_Reference_Card with the J primitives
missing.
In the German translation, which covers 3 pages, it is mentioned, under

Ah then, perhaps for the benefit of us ~non_farcebookers and in the
hopes of obtaining an ~open-utrality for your efforts you can find
some spot to place the paper? Eg a ~dropbox_account?
