ZTW.HST history file format and definitions

The ZTW.HST file is unicode when saved from v2 versions of ZTree.

The following list describes the different entries in ZTW.HST
ZTreeWin v.2.1.039

This unofficial list was composed over the years by testing of ZTree betas and
on basis of postings by Kim Henkel, John Gruener and others in the ZTree Forum.

Rules for entries in ZTW.HST:
-- -----------
1.) ZTW.HST contains ZTree's history lists. It consists of different sections and each sections can hold a maximum of 64 unmarked entries,
and an unlimited number of marked entries.

2.) Each line starts with a 2-char-abbreviation.
3.) Each separate 2-char-abbreviation corresponds to a separate history list section.
4.) The abbreviations consists of two lower case letters plus the "=" char.

     Example: ar=
5.) If an entry is marked as fixed the two lower case letters change to upper case and the "=" char changes to "+".

    Example: AR+
6.) If a history entry is marked as fixed with a char (A-Z or 0-9) for fast access the 3rd char ("=" or "+") of the abbreviation changes to the corresponding marker char.
    Example: ARA
