A DTM Logger trace message is an XML-formatted string of Unicode characters. This string is strictly limited to 4096 characters (8 KB). Strings longer than 4096 characters will be truncated.

If your message string includes XML escaped characters (such as "&", "<", or ">"), limit your string to approximately 3900 characters.

You can also print messages directly to the log file by using the wprintf function. However, your message will still be limited to 4096 characters.
