How does the JUMP *LABEL instruction work?

• A. The JUMP *LABEL instruction works only with the *LABEL instruction. Together they instruct the controller to go from the line of the JUMP*LABEL to the matching *LABEL within the same job and resume execution on the next line. The JUMP*LABEL can be used in combination with *LABEL to omit a portion of lines in the job or to create a repeat loop.
• B. The JUMP *LABEL jumps to a random line anywhere in the program.
• C. The JUMP *LABEL calls a subroutine by name.
• D. The JUMP *LABEL pauses until an external signal is received.

Answer: (A)

JUMP *LABEL is a flow-control instruction that transfers execution to a named destination inside the same job. It relies on a paired *LABEL that marks the destination. When this jump runs, control moves directly to the line containing the matching *LABEL and then continues with the line after that label. This lets you skip sections of code or create loops by jumping back to a labeled point, all within the same job. It does not jump to random lines, call a subroutine by name, or wait for an external signal, which is why the other behaviors don’t fit.
