On run {x} --- Getting 2 or 3 variables instead of just x

on run {x}

Thsi is the code i use to grab on variable sent by my real basic application

how would i get 2 or 3 variables on run?

on run {x, y, z}

The values will be assigned in the order they are passed.

First passed value = x
Second passed value = y
Third passed value = z

wow thanx
