BASIC language programs need to call a class library written in C#.

We created an intermediate DLL with a C language interface using C++/CLI. The invoke pipeline is: BASIC program—>dll (C++/CLI with C interface) —> dll (C# program).

This solution works fine on ICT devices with BT BASIC , but fails to execute on programs written in HT BASIC language version 9. Any suggestions on what to do?
