Instruction
If the corresponding sense switch is down (on), the
computer skips the next instruction. If the sense switch
is up (off), the computer takes the next instruction in
sequence (F igure 5. 3 -40) .
The computer causes an impulse to appear at the specified
exit hub of the control panel of the card punch attached to
Data Channel A, B, C, D, E, F, G, or H respectively
(Figure 5. 3-41).
If an impulse is present at the entry hub of the control
panel of the printer attached to Data Channel A, B, C, D,
_ E, F, G, or H respectively, the computer skips the next
instruction. If there is no impulse, the computer takes
the next instruction in sequence (Figure 5.3-42).
The computer causes an impulse to appear at the specified
exit hub of the control panel of the printer attached to Data
Channel, A, B, C, D, E, F, G, or H, respectively
(Figure 5.3-43).
