Direct variable access
NML allows a syntax to directly access (unnamed) variables in a switch-block by their NFO number:
var[<num>, <shift>, <mask>, <param>]
<num> is the NFO variable number, which is shifted
<shift> bits to the right and then and-masked with
<param> is only present for those variables (0x60-0x7F) which require a parameter.
This syntax should only be used when the required variable is not implemented in NML. Unless the variable is added by an unofficial patch (which will not be supported by NML), it's highly recommended to instead file a feature request at the NML tracker to implement the variable there.
NML allows to specify the used callbacks in the switch chain instead of the graphics block. See the description for details
