Numbers at end of Play strings

[PhilOfPerth]

Why is this question here and not in your other thread?

It seems some of the numbers are attached to "O" command which is to set the octave. Like "o3" and "o4" instead of using angle-brackets like in my "musak". Otherwise a few lines are inconsistent with the rest of the song and they do set the length of notes. Things have to be looked at more closely. This song is quite complex especially to do with only one voice.

Thanks for your response Minerva;
I didn't place this in my other thread because that question, I feel, has been answered very well by other members, and I wanted to start with a clearly stated question.

Some numbers are indeed related to the O command, but there are many that have no preceding letter.
Most of these are 8, but 4 and 2 are also present (see the sample four lines below), and I suspect they're superfluous,  or not covered by any of the Play documentation.

These are four examples, the last two being toward the end of the  piece.
M$ = M$ + "b8bbo2e8g#g#f#8d#8o1b8bbb8bbb8bbo2e8f#8g#8eg#mlb4bmsag#f#e8g#8e8o3bbb8bbb8bbo4e8f#8"
M$ = M$ + "g#8o4c#8o3g#8o4c#8o3g#8o4c#8o3g#8f#8e8d#8c#8g#g#g#8g#g#g#8g#g#g#8o4c#8o3g#8o4c#8"
M$ = M$ + "e8e8o2bbb8b8b8g#g#g#8g#8g#8eee8e8e8o1b8o2e8o1b8o2g#8e8b8g#8o3e8o2b8o3e8o2b8o3g#8e8b8g#8o4e4"
M$ = M$ + "p8eee8e8e8e8e4p8p16ee4p8p16o2ee2"

Edit: This is part of one of the lines (slightly modified):
m$ = "o4e8f#8"
PLAY m$
which plays E F#. But without the "8" it shortens the last note, so it is having some effect on play.
