Not sure what you want...
I find this description of "procedure?" at
https://www.cs.cmu.edu/Groups/AI/html/r4rs/r4rs_8.html
essential procedure: procedure? obj
Returns #t if obj is a procedure, otherwise returns #f.
(procedure? car) => #t
(procedure? 'car) => #f

What do you mean by "better"?
That said, there are several "native" ways of representing code in J:
1) as a sequence of characters (J can be thought of as a virtual
machine with ascii mapped as machine instructions)
2) as a file (typically represented as a file name)
3) as a gerund (you can use `

Hi,
I am translating scheme code that makes heavy use of delayed evaluation
(thunks). In scheme, there is a predicate 'procedure?' that returns a
boolean. I translated that into a check for a boxed string, which is the
representation I use for delayed procedures, which I then 'force' using ".@>
