I wonder what is the maximum number of PTTs (chapters).
On his site, Derrow says that the PTT number range from 1 to 99 (which is coherent with the displays of standalone players, usually limitted to 2 digits).
But he says also that the PTT number for the command LinkPTTN is coded on 10 bits, which gives a theorical maximum of 1023. The 6 remaining bits are used for the highlighted button number. (That could explain why the button number is coded in such a strange way.)
Note that JumpVTS_PTT use only one byte for the PTT, giving a maximum of 255.
So, what is the correct number? Someone know?

I need also the maximum number of Programs inside a PGC (LinkPGN uses one byte), and the maximum number of Cells (LinkCN uses one byte).

Thanks in advance!
