BRF; JUMP
39) BRF (Branch on Failure)
Function: The program branches only if the most recent "failure-reporting" command
failed in its execution.
Argument
[Program Address]
Explanation: Some commands, such as SEARCH, AUTOSTOP, MSF and MSR, and the
MLoad commands, set the player's "Success / Fail" flag as they finish execution. If the flag
indicates "Fail" when BRF is executed, program execution continues at the program address
specified by its argument. Otherwise, the next sequential instruction is executed.
Example: If MLOAD fails, try again. Otherwise, continue program execution.

40) JUMP
Function: "Branches" to a subroutine, recording a return address in Register 1.
Argument
[Program Address]
Explanation: Like a BRANCH command, JUMP causes the player to continue
instruction execution at the program address specified by the argument. It also stores, in
Register 1, the program address of the code byte that immediately follows the JUMP
command. This stored address can be used as a return address by a subroutine exit.
