separated by a “/:” (OR), and (in this case) at last is a “/;” (ELSE). For ASCII + Qual, there are four OR
conditions (specific time quality ranges) followed by one ELSE (worst quality range). The initial ordinal is
a space, meaning maximum time quality followed by a “.”, a “*”, a “#” and finally by the ELSE condition
of a “?”. A carriage return line feed “r” ends the string.

Input String Constructions Notes: Note that the ordinary method of starting the ASCII + Year broadcast is
using the B8 or O8 command as described on page 91. The ASCII + Year is identical to the ASCII + Qual
described above but includes the four-digit year followed by a space that precedes the Julian day. Notice
that there are two characters for year: y (0 to 99) and Y (2000 to 2xxx).
