A B C D E
Input: Input N and press key A. Press fa or fb. Put NMI in RY and NMC
in RX, and press fe. Press B and respond to prompts 1,2, ...,N with Qu,
Qu' etc.; or, input ITQL or mean QL and press C or fc. Input F or fjfo
and press fd or D, respectively. Press E and see dB attenuation for
dB:> 20. F>O and fjf o > I are required. Any of these can be changed
individually. Registers A-E are unused.
Note: uses explicit arrangement, as in HP Keynotes, January, 1977, pp. 4-5.
Keys A, C, D*, E, c, and d* solve for quantities if keyboard numbers are
not pressed before the function key is pressed; otherwise, the function
keys act as input. Keys B, a, b, and e are only single-purpose (input)
function keys.
Example: See Example 8.1,.Section 8.2.3.
Note: If A, C, D, E, c, or d don't run to completion when there was no
input, just press again. Also, don't stop the program with RjS, because
P:::; S is used.
• Iterates until round-off displayed is reached.
