figured it out, thanks.

well I bumped into something weird tho...

/scanline {
/verif 5 2b 3c
}

/verif {
echo $1
echo $2
echo $3}

gives insufficient parameters on the 1st echo.
when you change the 5 into a5 it works, there has to be text
in the parameter or it bugs, can anyone explain why?
that doesn't really makes sence to me tho.
