G-858BP Backpack Mag Operators Manual
Positions events and discontinuities are caused by MARK or END LINE key presses. Typically, a
discontinuity event is associated with the beginning of a line.
The C-program lines which BINTOASC uses to create these files are shown below.

fprintf(pAscFile, "%-2u %10.3lf %10.3lf %.2d:%.2d:%.2d.%.2d
%.2d/%.2d/%2.d %3u\r\n",
type, // 0 in this case
