How to Spawn a decal with script - info

I've got a basic hit-prediction scripted and whilst I can spawn applicable damage, explosion, etc at the end of the raycast, I've not worked out how to slap a decal at the position.

Anyone any ideas on spawning a decal with script? I'd hoped it would be a simple %decal = new decalData, datablock =, position=, etc but apparently it isn't ... or at least nothing happens and nothing in the console.
