   : (be read (@X)
  (^ @X (read)) )
   -> read

   : (? (read @A))

Alex, thanks for being so patient! I came up with this:

(be p_read ()
  (^ @ (read)) )

which looks to work so far ;-).

However I wonder if there is a way to catch and unify the read value to 
a variable.


For example in Prolog the predicate 'read/1' allows to catch in 
'read(Value)' where 'Value' can be passed to an other predicate. Can I 
do the same here.


Thanks,
Eric

Hi Eric,

Here too some Lisp function must be called.

However, it depends what you mean with "read": You can call the 'read'
function which reads s-expressions in Lisp syntax (or lists of tokens
when called with an additional arguments), or the lower-level 'char',
'line', 'till' etc. functions. Or even 'rd' for binary or PLIO reading.
