Forums Scripts & Popups message all results to one line

atm I have :

while ($somefunction) && (%a < %b) {
inc %a
.msg $chan  output of function
if (%a > %b) { halt }
}

so if %b = 10 it will output a message on 10 lines

how can I get it to delay all the outputs and just put them on one line as a single /msg ?

thanks
