The new behavior in 9.3.0 occurred after introducing error reporting for out of range indices on strings. I looked on the 9.3 release notes and did not see anything related to this, or the similar new behavior on lists. Could you please direct me to an explanation of the new behavior. This change i...

On version 9.3, I get the following: newLISP v.9.3.0 on OSX UTF-8, execute 'newlisp -h' for more info. > (char "") string index out of bounds in function char > Prior to 9.3, this used to return 0. Shouldn't this be still the case being that an empty string by definition (at least in C, which I thou...

I was perusing through K+R "The C Programming Language" and came across this tidbit on bit operations: http://www.angrypacket.com/~maq/getbits.png And the (p + 1 - n) doesn't make sense, as it would seem you actually want to do (p - n). I wrote the same function in newlisp both ways: (p - n): http:/...

I set a string to the following: (set 'command-line "woot -r 45 -w 46") And then I want to alternate through the command line options by comparing against a list of flags that I'm looking for. Say: (set 'opts '("r" "w")) So I want to...

Thanks for the prompt reply. However, a read-buffer does not fix it. With: (set 'in (open "foo2.png" "read")) ;;(set 'ifile (read-file "foo2.png")) (read-buffer in 'ifile 100) (close in) (println "length of ifile " (length ifile)) (println "length through a get-string " (length (get-string (address ...

Why is it that I get different values from the following two length calls: (set 'ifile (read-file "foo2.png")) (println "length of ifile " (length ifile)) (println "length through a get-string " (length (get-string (address ifile)))) (exit) --OUTPUT-- maq:maq $ ./test.lsp length of ifile 90 length t...
