did not exist. Diagram B from the TR bit and interlock example could be re-
drawn as shown below using a jump. Although 01 has been used as the
jump number, any number between 01 and 99 could be used as long as it
has not already been used in a different part of the program. JUMP and
JUMP END require no other operand and JUMP END never has conditions
on the instruction line leading to it.

This version of diagram B would have a shorter execution time when 00000
was OFF than any of the other versions.
The other type of jump is created with a jump number of 00. As many jumps
as desired can be created using jump number 00 and JUMP instructions us-
ing 00 can be used consecutively without a JUMP END using 00 between
them. It is even possible for all JUMP 00 instructions to move program
execution to the same JUMP END 00, i.e., only one JUMP END 00
instruction is required for all JUMP 00 instruction in the program. When 00 is
used as the jump number for a JUMP instruction, program execution moves
to the instruction following the next JUMP END instruction with a jump num-
ber of 00. Although, as in all jumps, no status is changed and no instructions
are executed between the JUMP 00 and JUMP END 00 instructions, the pro-
gram must search for the next JUMP END 00 instruction, producing a slightly
longer execution time.
Execution of programs containing multiple JUMP 00 instructions for one
JUMP END 00 instruction is similar to that of interlocked sections. The follow-
ing diagram is the same as that used for the interlock example above, except
redrawn with jumps. The execution of this diagram would differ from that of
the diagram described above (e.g., in the previous diagram interlocks would
reset certain parts of the interlocked section, however, jumps do not affect
the status of any bit between the JUMP and JUMP END instructions).
