Starting Blackbox from runlevel 3

[Thrasher]

I have searched all over and cant find the command to start blackbox.
I boot into runlevel 3 and need to know the command to start blackbox. I do not want to make it my default WM. I have tryed numerous commands but cant seem to find the right one.

Can someone give me the command with startx to get blackbox up?

Im on a redhat 9 machine at moment but also have slackware 9.1 that I want to use it on. I know it works because I have changed to runlevel 4/5 and opened it from there.
Thx in advance.

[saturn-vk]

startx /path-to-exec/blackbox

or

X & blackbox -display :0

for slackware:

go to /etc/X11/xinit

copy xinitrc.twm to xinitrc.blackbox (or whatever). then edit it, and instead of twm, place blackbox.

Thank you much !
Now I can stay away from runlevel 4/5
