Per definition the user messages are all max. 64 chars long!
but in game they are longer. i saw the teh max. length of user messages are 95 (or 96 with the #0 at the end).

so why InSim only provides 64 chars instead of 96?

is this a know issue or do i something wrong?

definition:
struct MsgOutSplit // 64 chars - user messages if ISF_SPLIT_MESSAGE flag is ON
{
char Id [4]; // MSS + zero
char UName [24]; // user name
char PName [24]; // player name
char Msg [64]; // text message from user
}

and therefor also the message which i can send to LFS via InSim should be 96 long...

Hmm, I dont know, but maybe in the LFS beginnings where InSim was implemented there were only 64 characters allowed?!?
I dont make sure if its 96 like you said...

But I dont believe that Scawen will edit the package(size) because then all mods using this have to change it too.

ISF_SPLIT_MESSAGE flag is ON

The message is split over multiple packets according to that, although i've not really looked into the messaging system in that much depth it seems to me that there's multiple ways to do messages in insim. I think to unsplit them you use MSO or something.

using MSO instead doesn't help...
the 128 chars long message also contains only 64 chars of the user message!
