Hello Lutz:
I download your 10.4.6 binary newlisp.exe from http://www.newlisp.org/downloads/development/Win32-utf8/
, run it on windows 7. It seems it doesn't need newlisp.dll.
what can I use this dll for?
newlisp.exe - or just the 'newlisp' executable on unix - is the only thing you need to run newLISP. Always has been like that. newlisp.dll is only needed if you want to run newLISP embedded in another application, like calling it from Excel, Visual Basic, C or other programming languages.
