NB. Load it using 0!:0 or similar or
NB. paste it on an J editing window and use Crtl-A Crtl-E or
NB. of course, load it using a hot key (or replace '=.' by '=:' if you
must)
NB. A word is a noun, verb, adverb or conjunction

an=. <@:((,'0') ,&< ]) NB. Atomizing words (monadic verb)
Cloak=. (0:`)(,^:) NB. Cloaking (the atomic
representaions

NB. Defining cv in terms of itself...

cv=. (train f. cv at (<x rank _ c)) f.adv NB. Constant verb
u ( cv=. ( >cv at (<x rank _ c)) f.adv )
NB. Constant word (adv)
NB. (cv is to words as c is to nouns)
assert (CRLF cv _) -: CRLF

NB. Fetch and From...
pointers=. (<: o - o i.)`i. @.(0<])
Fetch=. (] amper {:: cv)e o pointers f.adv NB. Verbs mnemonics
pointers
NB. (e.g., ( 'u0 u1 u2 u3'=. 4 Fetch ) j ( 'v0 v1 v2 v3'=. _4 Fetch

mRS=. (`'') (<&.:train f.av) (`,)(`]) (`:6) (train f. @:

NB. Monadic recursion scope
assert (1 + (1:`(* $:@<:)@.*) mRS 4) -: 25 NB. Factorial
fixed
dRS=. (`'') (<&.:train f.av) (`,) (`]) (,`) ([`) (`:6) (train f. @:
)(&:(an f.))
NB. Dyadic recursion scope
assert (3 (1 + (1:`(%~ * $:&:<:)@.(*@:[))dRS) 7) -: 36 NB.
Binomial fixed
mRS is properly assigned and works as intended from file,
mRS
((((((`'')(((`'')(&(<&.:(,^:(0:``:)&6 :.(<@:((,'0') ,&<
])))@:[)))((`_)(`:6))))(`,))(`]))(`:6))(,^:(0:``:)&6 :.(<@:((,'0') ,&<
]))@:))(&:(<@:((,'0') ,&< ])))
but trying to to assign it to this linear representation produces a
syntax error
mRS =: ((((((`'')(((`'')(&(<&.:(,^:(0:``:)&6 :.(<@:((,'0') ,&<
])))@:[)))((`_)(`:6))))(`,))(`]))(`:6))(,^:(0:``:)&6 :.(<@:((,'0') ,&<
]))@:))(&:(<@:((,'0') ,&< ])))
|syntax error
is this a bug in linear representation? is it directly assignable?
