[PD] setting Messages

[HENRY Damien]

Dear list.

I need some help !!!
I whant to change what's in a message in a sub patch.

the $1 passing mecanisme don't work for message because they use $1 for 
another purpose.

I can use a "set $1" message instead and use an inlet.

but $1 can't contains space. the "/" don't work the same way than in sh (due 
to tk i have read somewhere) and cotting ("{''}") don't look to work.

1) is it possible to manage space in message ?
2) is there a way to "set" a complex message via an inlet ?

thanks
