4.5 Command Formats
Level III commands on the LD-V8000 are expressed as “Command Mnemonics”, so
they are easier to remember. “Command Mnemonics” are also used for Level III
control of the LD-V4400, CLD-V2400, LD-V2200, the LC-V330 and the discontinued
LD-V4200. (See
Technical bulletin #143
,
Command Mnemonics for Pioneer
Industrial LaserDisc Players
.) Some commands are preceded by an “argument”
that may be a specific “address” or an “integer”.
Command Mnemonic

PL (Play);
Pl (Play);
pl (Play)

occurs. An argument consists of one of the following:
