Integer type data processing instructions
F289 16-bit data
zone control
ZONE S1, S2,
S3, D
When S3 < 0, S3 + S1 → D
When S3 = 0, 0 → D
When S3 > 0, S3 + S2 → D
10
F290 32-bit data
zone control
DZONE S1, S2,
S3, D
When (S3+1, S3) < 0,
(S3+1, S3) + (S1+1, S1) → (D+1, D)
When (S3+1, S3) = 0, 0 → (D+1, D)
When (S3+1, S3) > 0,
(S3+1, S3) + (S2+1, S2) → (D+1, D)
