IBITS
— Bit extractionIBITS
extracts a field of length LEN from I,
starting from bit position POS and extending left for LEN
bits. The result is right-justified and the remaining bits are
zeroed. The value of POS+LEN
must be less than or equal to the
value BIT_SIZE(I)
.
RESULT = IBITS(I, POS, LEN)

POS | The type shall be INTEGER .

INTEGER
and of the same kind as
I.
