You can use the command AP FPRINT to append contents to a file created with 4D. This command is strictly for windows because it uses ANSI C command.

Here is a simple procedure that will create a simple text document:

$doc:=Create document("")
If (OK=1)
CLOSE DOCUMENT($doc)
port:=AP fopen (document;0)
AP FPRINT (port;"hello world")
AP FCLOSE (port)
End if
