Sometimes you probably have written something like this:
s := Format('Hello %s, your name is %s %s', [FirstName, FirstName, LastName]);

in the format string like this:
s := Format('Hello %0:s, your name is %0:s %1:s', [FirstName, LastName]);
Just one more example from a code generator I am currently writing:
TableName := 'Customer';
...
s := Format(' f%0:sTableAuto := T%0:sTableAuto.Create(f%0:Table);', [TableName]);
...
s := Format(' f%0:sTableAuto := T%0:sTableAuto.Create(f%0:Table);', [TableName]);
which results in
s := ' fCustomerTableAuto := TCustomerTableAuto.Create(fCustmerTable);';
