This file has a similar structure as the message file (MDATAx.DAT). Only the "Count" field is missing, there are exactly 100 records.

The texts are encrypted like the messages: Each ASCII code is increased by 13. Line ends are encoded as CR+LF (0Dh 0Ah, encrypted as 1Ah 17h).

Unused help texts contain the text "RESERVED ... nn".

This is a testing version.
