VDU 23,command,nine parameters
Miscellaneous commands.
Though few of the commands use all of the nine parameters, they must always be present. In BASIC, you can use | to add eight zero bytes:
VDU 23,0,10 |
=VDU 23,0,10,0,0,0,0,0,0,0,0
Any extra zero bytes remaining after the 9 bytes used by the VDU 23 command are ignored (VDU 0 is a no-op).
