Re: How to display some text in Pilog - SOLVED

Hello Alex, Thank you very much, that's it. In fact, I have tried this solution before asking on the list, however as I am still not very fluent in Lisp I have written : : (be intro (prin "Hello world\n") ) without the two >> () << at the beginning of the defintion of the predicate!!

typo in tutorial re 'till' ?

Not a big deal but... it seems there is one too many ')' on the end resulting in bad input rather than "fact" : (in "@doc/fun.l" (from "(de ") (till " " T))) -> "fact"

read in Pilog

Is there a way to have something similar to 'read' in Pilog? Thanks, Eric -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe

Re: read in Pilog

Hi Eric, > Is there a way to have something similar to 'read' in Pilog? 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 argument

Re: read in Pilog

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 'Val

iterate over list until you find a match

I'm just wondering what my options are re doing this (de mmbr (Trgt L) (for Ele L (if (== Ele Trgt) (println "found so exit with true") (println "try next") ) ) (prinl "list exhausted so return false") ) (mmbr 'B '(A B C)) I only know how to itera
