CGTalk - Simple for loop ?

This seems to be a pretty simple mel question but Im hopeless with mel and tried to figure it but got stuck.

I have for example 500 pCube called pCube1 - 500.
They are all active rigids and want to connect a gravity field to them all. For some reason Maya doesn't let me select all the rigids then go to the menu and apply gravity, it looks as though I can only do it through the dynamics relationship editor one by one, ha ha ha, or use mel.
I know this is the mel to connect gravity to one cube...

connectDynamic -f gravityField1 pCube1;

and that I should use a for loop and an array but thats about it, anybody?

simpliest way

for ($i=1; $i<=500; $i++)
{
connectDynamic -f gravityField1 ("pCube" + $i);
}

Hey Aikiman,

Glad you solved it with this code, but i don't understand what the problem was to start with.
Select all 500 cubes, then go to Fields Gravity. All cubes will be made Rigid Bodies and have the gravity field applied to them. It also works if u already have the cubes as rigid bodies.
If you have the cubes and an existing field (gravity for ex), select all cubes then the field (last) then go to field>affect selected objects.

Works every time, but hey no harm in learning some mel either :D

TAKADS,
In theory (and practice) this should work but I think it must be a bug in the Mac version, hence the hard coding.
