In Delphi (10.3) is there a way to test if a text file was opened via Rewrite or via Append?
I've found this: Checking File is Open in Delphi but it doesn't help as it only says if file is opened for Read or Write.
Note that I can use a global Boolean, initialized to True if I open the file as Append, and to False if Rewrite, but I'm curious to know if the is another way.

TTextRec(txt).Mode is fmOutput for Rewrite and fmInOut for Append (look in system.pas)
