ARCHOS box rock - Manual (Page 68)

%pe : Total Number of Playlist Entries
%pm : Peak Meter (Recorder only) - the entire line is used as volume peak meter.
%pn : Playlist Name (Without path or extension)
%pp : Playlist Position
%pr : Remaining Time In Song
%ps : Shuffle. Shows 's' if shuffle mode is enabled.
%pt : Total Track Time
%pv : Current volume
Conditional Tags (If/Else block):
%?xx<|> : Conditional: if the tag specified by "xx" has a value, the text between
the "<" and the "|" is displayed, else the text between the "|" and the ">" is
displayed. The else part is optional, so the "|" does not have to be specified if no
else part is desired. The conditionals nest, so the text in the if and else part can
contain all % commands, including conditionals.
Next Song info
You can display information about the next song - the song that is about to play
after the one currently playing (unless you change the plan).
If you use the upper-case versions of the three tags: F, I and D, they will instead
refer to the next song instead of the current one. Example: %Ig is the genre name
used in the next song and %Ff is the mp3 frequency.
Take note that the next song information WILL NOT be available at all times, but
will most likely be available at the end of a song. We suggest you use the
conditional display tag a lot when displaying information about the next song!
Alternating sublines
It is possible to group items on each line into 2 or more groups or "sublines". Each
subline will be displayed in succession on the line for a specified time, alternating
continuously through each defined subline.
Items on a line are broken into sublines with the semicolon ';' character. The
display time for each subline defaults to 2 seconds unless modified by using the '%
t' tag to specify an alternate time (in seconds and optional tenths of a second) for
the subline to be displayed.
Subline related special characters and tags:
; : Split items on a line into separate sublines
%t : Set the subline display time. The '%t' is followed by either integer seconds (%
t5), or seconds and tenths of a second (%t3.5).
Each alternating subline can still be optionally scrolled while it is being displayed,
and scrollable formats can be displayed on the same line with non-scrollable
formats (such as track elapsed time) as long as they are separated into different
sublines.
