The signal options list (the list of setting optional signal subobjects) has a maximum length of 30. But the maximum possible number of subobjects is 32.
For a signal which has subobj 30 and 31 defined, these two subobjects cannot be accessed to set or reset.

SubObj 30 ("Route not Allowed") is not shown in list.

Is it a limitation of the OR code itself?
Or from TSRE5?

[roeter]

The max. of 32 is a general data limit. Each subobj is represented by a bit, so a 32-bit word can hold 32 states. In the signal definition in the world file, this state is shown as a hex-representation of that word, e.g. :

		SignalSubObj ( 00000d03 )

The problem that states 30 and 31 are not shown in the list is a TSRE error.
