Sorry, my fault. Back in the good old days, we thought it was neat to
save a little code here & there: I figgered we'd just require that the 
INIT resource have its resLocked bit set, and good old Resource Manager 
would lock it for us. 

I'm told by the folks who now deal with such things that they'll add the
HLock in the next version.
