just to show one of the many ways this can be done.
you could use tokens
look into /help $gettok
and /help $numtok
then just do !emmm a b c d e f g

on *:TEXT:!emmm*:#:{ msg # emmm answer : $gettok($2-,$r(1,$numtok($2-,32)),32) }

you may want to add error checks and flood control to it

or maybe just do

alias emmm echo -a emmm answer : $gettok($1-,$r(1,$0),32)
