6.18 JUO Jump if Unordered Format Description Status word Example JUO Address Description Symbolic name of jump destination. Logic Control Instructions If status bits CC 1 = 1 and CC 0 = 1, JUO interrupts the linear program scan and jumps to a jump destination. The linear program scan resumes at the jump destination. The jump destination is specified by a jump label. Both forward and backward jumps are possible. Jumps may be executed only within a block, that is, the jump instruction and the jump destination must lie within one and the same block. The jump destination must be unique within this block. The maximum jump distance is -32768 or +32767 words of program code. The actual maximum number of statements you can jump over depends on the mix of the statements used in your program (one-, two-, or three word statements). Status bits CC 1 = 1 and CC 0 = 1 when • A division by zero occurred • An illegal instruction was used • The result of a floating-point comparison is "unordered," that is, when a invalid format was used.
