Explanations:
1. SCLP instruction performs a proportional calculation according to the internal slope equation
as well as the parameters set in this instruction.
2. Settings of S 2 for 16-bit instruction (occupies 4 consecutive devices):
Device No. Parameter Range
S 2 Max. source value -32768~32767
S 2 +1 Min. source value -32768~32767
S 2 +2 Max. destination value -32768~32767
S 2 +3 Min. destination value -32768~32767
3. Settings of S 2 for 32-bit instruction (occupies 8 consecutive devices).
Device No.

4. Operation equation in the instruction: D = [(S 1 – min. source value) × (max. destination value –
min. destination value)] ÷ (max. source value – min. source value) + min. destination value
5. The equation to obtain the operation equation of the instruction:
y = kx + b
where
y = Destination value (D)
k = Slope = (max. destination value – min. destination value) ÷ (max. source value – min.
source value)
x = Source value (S 1 )
b = Offset = Min. destination value – Min. source value × slope
