Function/trigger call from external program

Hi, does someone have an idea what option I have to call any Navision function or trigger from an external program (without starting the NF-client)? I know it is not working with the C/FRONT and C/ODBC interface - is there another option? Thanks

You can use NAS.

How can I use NAS? Please give me more detail

Start with the manuals on the CD and read about Application Server //Lars

I read it but It’s about the detail of Installation.Could you please tell me the exactly code to call it? I really want to make it work.I need it.Please help !
