VFP is a weakly typed language, that is, the compiler allows operations such as assignment and comparison among variables of different types. For example, VFP allows the value of a variable to be cast to another type. The ability to use variables of different types in the same expression promotes flexibility as well as efficiency.

Note: Strong typing in Visual FoxPro 7/8/9 SP2 is not enforced at compile or run time, but is used primarily at design time.

Do you know what language this code was written in?

If it compiles in one, it should in another with minimal work.

Customer = "Smith"
Customer = CreateObject("Excel.Application") 
Customer = .T. 

LOCAL CustomerName AS String

LOCAL CustomerName AS String
CustomerName = 10+5

dc.users.InsertOnSubmit("us");

dc.users.InsertOnSubmit(us);

using (MyDataContext dc = new MyDataContext())
{
    var userName = (from u in dc.tblUsers
                    where u.Id = someId
                    select u.UserName).FirstOrDefault();


    user us = new user
