Hello List, it's been some time .. ;-) I'm playing around a bit with hex<->ascii conversion in PicoLisp, and I have the problem that (char 0) = NIL
(hex "00") -> 0 : (char (hex "00")) -> NIL and disappears from the resulting ascii string. : (setq X "232302000000010001000F00000000000000323032342D30322D303931302D35342D3035202000000000000000002424") : (setq Y (chop X)) : (pack (make (while Y (link (char (hex (pack (cut 2 'Y)] -> "##^B^A^A^O2024-02-0910-54-05 $$" So how would it be possible to convert the ascii string back to the original hex string, when all the "00" are gone in the ascii representation? Shouldn't the (char 0) representation print to something like ^N or so too, like (char 1), (char 2) etc? When I try this online converter, the "00" are maintained as blanks: Hex to ASCII Text String Converter (rapidtables.com) <https://www.rapidtables.com/convert/number/hex-to-ascii.html> [image: image.png] and here is another representation that seems to enable the hex -> ascii -> hex conversion, getting exactly the same hex string in the end as in the beginning (not exactly the same conversion as above! just an example how it might look) : [image: image.png] Cheers Thorsten
