No, I don't see any problem here. There is no literals for private types,
(unfortunately). But if the type Fully_Qualified_File_Name (or whatever we
called it) should have literals, they would be record aggregates. So we
would write something like:
File : File_Type;
begin
Open
( File => File,
Mode => In_File,
Name =>
( Volume => "C:",
Directory => ("Documents and Settings", "me", "work"),
Name => "test",
Extension => "txt"
) );
the above is impossible due to language limitations, but we could:
File : File_Type;
begin
Open
( File => File,
Mode => In_File,
Volume => "C:",
Directory => ("Documents and Settings", "me", "work"),
Name => "test",
Extension => "txt"
);
or / and
File : File_Type;
begin
Open
( File => File,
Mode => In_File,
Name =>
Name
( Volume => "C:",
Directory => ("Documents and Settings", "me", "work"),
Name => "test",
Extension => "txt"
) );
