Adding numbers in game states

[James W. <jfc...@ya...>]

Hi all,
 
How does one add a number to a variable? 
For example, here's a state, as defined in Main.lua:
state.blahhumblah=1
 
Now, in a node.lua, I want to do something to this effect:
 
state.blahhumblah=+1
 
So that whenever a function is run it'll increase the state's value by 1. Or subtract it, etc.
 
Anyone know how to do this? It's quite common in other systems, Python, TADS, Inform...
 
Thanks,
  James

state.blahhumblah = state.blahhumblah + 1

For issues such as these, the Lua reference manual is your friend: 
<http://www.lua.org/manual/> (Pipmak still uses Lua 5.0, not 5.1; this is 
supposed to change at Pimak 0.3.0).  In my opinion, Lua is one of the weirder 
languages--perhaps because it is not a general purpose language?--so keep it 
on hand whenever using Lua ;).  (I still prefer it as a game engine's 
interface, though.)

state.blahhumblah = state.blahhumblah + 1
