[Jprogramming] is there a way to tell if a string evaluates to an adverb

[Dan Bron]

Sorry for the short note, in on the subway 

   ncS=:3 :'z=.y 1 :y label_. nc<''z'' ' NB. nameclass of string

   ncS"0@;: 'a: + / @'
0 3 1 2

   isAdverb=: adverb = ncS

   isAdverb"0@;: 'a: + / @'
0 0 1 0

   arString=:3 :'z=.y 1 :y label_. 5!:1<''z'' '

   arString '//' NB. train of adverbs
+---------+
|+-+-----+|
||4|+-+-+||
|| ||/|/|||
|| |+-+-+||
|+-+-----+|
+---------+
   arString '+@' NB. bonded conjunction
+---------+
|+-+-----+|
||4|+-+-+||
|| ||+|@|||
|| |+-+-+||
|+-+-----+|
+---------+

   isAdverb '//' NB. train of adverbs = adverb
1
   isAdverb '@+' NB. bonded conjunction = adverb
1

See Dictionary $II.F for the definition of adverb trains and bonded conjunctions (described after forks and hooks).
