Program Lines: Description
Starting point for input of coefficients.
)
Loop–control value: loops from I to 12, one at a
time.
!
L
Stores control value in index variable.
Checksum and length: 9F76 012.5
Starts the input loop.
"!1L2
Prompts for and stores the variable addressed by
i.
L
Adds one to i.
!
If i is less than 13, goes back to LBL L and gets the
next value.
!
Returns to LBL A to review values.
Checksum and length: 8356 007.5
