where: SS1(start sentinel track 1) = %
SS2(start sentinel track 2) = ;

ES(end sentinel all tracks) = ?

Start or End Sentinel: Characters in encoding format which come before the
first data character (start) and after the last data character (end), indicating the
beginning and end, respectively, of data.
Track Separator: A designated character which separates data tracks.

data, to separate card reads.
LRC: Check character, following end sentinel.

*Note: The <CR> commands shown above for tracks 1 & 2 and 2 & 3 denote the
default character for this position, the Track Separator position. The <CR> command
shown for track 3 denotes the default character for this position, the Terminator posi-
