[Help-bash] confuse about bash

[PurencoolGmail]

Hi Bash Expert,

I have a bash script that says this

HOUSE=null;
echo HOUSE;

What I am trying to do from the command line is set variable when the 
script
loads but I can't seem to fined anything on the web about it. I was 
hoping to
to something like this

> bash myscript.sh set HOUSE=foo

Is this possible?

Thanks
