Use TextFile instead of Text, use AssignFile instead of Assign. Alternatively prepend both Text and Assign with system. (note the dot!).

Explanation:

The code most likely is inside a TForm. TForm descends from TPersistent. TPersistent has a .Assign() method, which is totally unrelated to the Assign() of the system unit.

When compiling your code, the compiler needs to know which Assign() to use. It finds first the TPersistent.Assign, stops searching and gives an error because it has different arguments from the system version.

By prepending your "text" and "assign" with system: system.text, system.assign, the compiler does not search in TPersistent and finds the correct routines.
