Simple Blinking Light Expression, please!

[MikeVerta]

I would like to write an expression to control a parameter (Renderman's glowGain) to toggle between the values 0, and 1 every frame.  0,1,0,1,0... etc.  I know this is dead simple.  Except for me, evidently.  

Would appreciate some help!

Thanks,

_Mike

I'm not in front of Maya but maybe something like this might work?

glowGain = frame%2;

Yep, that did it!  What does the % indicate?
