I keep going back here all the time, a few I can remember off-by-heart though.
Unfortunately there are documentation issues with g-codes, while each normally does roughly what is described, each printer firmware has its own quirks, which are not well published. But most of the common ones are fairly well defined & predictable these days.

As per original Gcode, All the chunks of the command are a letter followed by a number (yes, some rare exceptions like the "display message" command), so these are T0 (zero) and P0 (zero).

P is usually used for generic Parameters - if a command only takes one, it's often P or S (a loose convention of sorts)
T is a special Tool select command - T0 means you're selecting extruder 0. The S parameter here is actually the temperature!

Note that the M109 command is not setting the bed temp - it's setting the extruder temp, then waiting for that temperature to be reached (110C). Bed temperature is typically set with M140, set-and-wait with M190.

What does the bolded text mean in the GCode sample below?  ("TO" and "PO") or is it T0 and P0?

Is it "T" or "P" and a numeric value?  Maybe "T" means TEMPERATURE?

M103 (disable RPM)
M73 P0 (enable build progress)
G21 (set units to mm)
G90 (set positioning to absolute)
M109 S110 T0 (set HBP temperature)
M104 S240 T0 (set extruder temperature) (temp updated by printOMatic)

Thanks
