			== Old-style callbacks ==
			NML allows to specify the used callbacks in the switch chain instead of the graphics block.
			See the [[NML:Old style callbacks\|description]] for details

== Direct variable access ==
NML allows a syntax to directly access (unnamed) variables by their NewGRF number:
<pre>
value = param[<num>, <bit>, <mask>, <param>]
</pre>
where <code><num></code> is the variable number, <code><bit></code> is the the first bit read from that variable, <code><mask></code> is a mask applied to the variable and <code><param></code> is only present for those variables which require a parameter.
