Please use this command, when outputted to the error message of NESASM.
Some tracks are arranged in the place of a higher rank from 8 K bytes, and an error is avoided.
The numerical value of 1-14 enters by the track number, 1 corresponds to A track and [num] has become 2=B, 3=C, --P=7 below.


#BANK-CHANGE [num0],[num1]

It is the extended form of the above-mentioned bank switching.
As for [num0], the value of 0-2 enters by the bank number.
The numerical value of 1-14 enters by the track number, 1 corresponds to A track and [num1] has become 2=B, 3=C, --P=7 below.
Incidentally the following is doing the same thing.

	#BANK-CHANGE	n
	#BANK-CHANGE	0,n

Since banks 1 and 2 were the storage places of DPCM, when this command is used, restriction produces them at the time of DPCM use. Be careful.
