Disable Dialog within dialog

[renn_inoue]

I was interested in incorporating a system where dialog options were removed as you read them (like in the recent stellar Apprentice).  But I can't find anything in the manual about how script functions change in the dialog script.  

For example, while you normally set a global int as such:  SetGlobalInt(10,1);

in dialog script you call the function as: set-globalint 10 1

So, I figured the SetDialogOption would look similiar in dialog script, but it gives an error.  

Can someone give me the correct script for SetDialogOption when called in a dialog script?  Or better yet could someone point to the part in someone's previous tutorial (or manual) where it discusses how calling functions change in dialog script?  I tried the manual first.  I couldn't find it.  Thanks in advance.

Manual -> tutorial -> setting up the game -> conversations... There are all the functions that'll work in dialogs...

Ahh, option-on and option-off.  Sorry.  Didn't see those.  Thanks AJA.
