N7:4 - (N7:6 * N7:10)
If the input conditions go true, evaluate the Expression N7:4 -
(N7:6 * N7:10) and store the result in the Destination (N7:3).
The CPT instruction can perform these operations: add (+),
subtract (-), multiply (*), divide (|), convert from BCD (FRD),
convert to BCD (TOD), square root (SQR), logical and (AND),
logical or (OR), logical not (NOT), exclusive or (XOR), negate (-
)
clear (0), and move, X to the power of Y (**), radians (RAD),
degrees (DEG), log (LOG), natural log (LN), sine (SIN), cosine
(COS), tangent (TAN), inverse sine (ASN), inverse cosine (ACS
)
inverse tangent (ATN), and complex expressions (up to 80
characters)

If input conditions go true, take the arc cosine of the value
in F8:19 and store the result in F8:20.
