JB JBT JBF
JB, JBT, and JBF "break out" of any currently executing U or G command. Execution continues with the command that follows the U or G command list. You will receive an error if you try to execute JB outside of a U or G.
JBT only breaks out if the condition register is TRUE; otherwise, execution continues normally. Similarly, JBF only breaks out if the condition register is FALSE.
