In particular, look at the examples using strings or string arrays.
I think one of the changes in the latest release of Visual APL is to include handling for data type decimal - if you can demonstrate where the latest release breaks compatibility with another version, I am sure Joe will be willing to investigate.
I will shortly be looking at your requirement. In reply to your specific questions:
For literal arguments between C# and Visual APL:
- Do not use strong typing in Visual APL.
- Enclose each literal or element if using arrays.
- In C#, use object or object[,]. Cast each element to string, if/where necessary.
- In Visual APL, use disclose, if/where necessary.
For other types, (e.g int) strong typing does not create problems.
