JNVT JUMP IF OVERFLOW-TRAP FLAG IS
CLEAR. Tests the overflow-trap flag. If the
flag is set, this instruction clears the flag and
passes control to the next sequential
instruction. If the overflow-trap flag is clear,
this instruction adds to the program counter
the offset between the end of this instruction
and the target label, effecting the jump. The
offset must be in range of –128 to +127.
if VT = 0 then
PC
← PC + 8-bit disp
JNVT cadd
(11010100) (disp)
NOTE: The displacement (disp) is sign-
extended to 16 bits.

JST JUMP IF STICKY BIT FLAG IS SET. Tests
the sticky bit flag. If the flag is clear, control
passes to the next sequential instruction. If
the sticky bit flag is set, this instruction adds
to the program counter the offset between the
end of this instruction and the target label,
effecting the jump. The offset must be in
range of –128 to +127.

JV JUMP IF OVERFLOW FLAG IS SET. Tests
the overflow flag. If the flag is clear, control
passes to the next sequential instruction. If
the overflow flag is set, this instruction adds
to the program counter the offset between the
end of this instruction and the target label,
effecting the jump. The offset must be in
range of –128 to +127.
