56) RRS (Read Rear Switch)

Function: RRS puts the sixteen user function switch settings into R0.
Argument
[Ignored]
Explanation: This command reads the sixteen user-function switches (1 - 16), counting
an "ON" switch as a "1" bit and an "OFF" switch as a "0" bit. The 16-bit value is stored in
Register 0.
Note: On the LD-V8000, these on-screen parameter "switches" are accessed by pressing
the player's "Display" button while turning on the player's power. Then, the user-
parameter switch settings can be viewed using the player's Scan Forward or Reverse
buttons. They can be changed using the Step Forward and Step Reverse buttons. Switch
1 is the least significant and Switch 16 is the most significant. See LD-V8000 Level I &
III User's Manual/Programmer's Reference Guide TP 113 v.2.0 3/91, Section 2.4.
Example: If user function Switch 12 is ON (1), access Frame 1000, otherwise access
Frame 2700.
