Usage Notes
Examples
STORE VECTOR
hexword...
identifies the data you wish to store in consecutive elements of the vector
register you specify. The hexword operands may each be up to eight
hexadecimal digits. If the value is less than a fullword, it is right-adjusted in the
register element, and its high-order bytes are filled with zeros. If you specify two
or more hexwords, they must be separated by one or more blanks. If the
number of hexwords listed plus the starting element number exceeds the
section size, the valid hexword is stored, and an error message is issued.
hexdword...
identifies the data you wish to store in consecutive elements of the vector
register pair you specified. Each hexdword operand may be up to 16
hexadecimal digits. If the value is less than a doubleword, it is left-adjusted in
the register element, and its low-order bytes are filled with zeros. If you specify
two or more hexdwords, they must be separated by one or more blanks. If the
number of hexdwords listed plus the starting element number is larger than the
section size, the system stores the valid hexdwords and ignores the excess
hexdwords.
VSR hexword...
stores the data in hexword1 (and hexword2 if you specify hexword2) in the
virtual machine’s vector status register. Each hexword operand may be up to
eight hexadecimal digits. If the value is less than a fullword, it is right-adjusted
in the register word being altered, and its high-order bytes are filled with zeros.
If you specify two or more hexwords, they must be separated by one or more
blanks. This fullword value is then checked to conform to the architecture of the
vector status register. The system corrects any inconsistencies.
VMR hexword...
stores the data in hexword1 and the other specified hexwords in the virtual
machine’s vector mask register. Each hexword operand may each have up to
eight hexadecimal digits. If the value is less than a fullword, it is left-adjusted in
the word, and its low-order bytes are filled with zeros. If you specify two or
more hexwords, they must be separated by one or more blanks. The number of
bytes that can be stored in the VMR is limited to the section size. If the
combined operand is longer than the length of the vector mask register, the
system ignores the excess digits.
VAC hexdword
stores the data in hexdword in the virtual machine’s vector activity count. The
operand may represent up to 16 hexadecimal digits. If the value stored is less
than a doubleword, it is right-adjusted in the word, and the leftmost bits are
filled with zeros. This hexdword value is then checked to conform to the
architecture of the vector activity count. The system corrects any
inconsistencies.
1. STORE VR and STORE VP turn on the vector in use and change bits
corresponding to the register or pair being changed. If the in-use bit is already
off, the elements of that register pair contain zero because nothing is stored in
them.
To store hexadecimal values 4E5400005E450000 and 4E5500005E550000 into the
vector register pair 6 and 7, enter st vp6 4e5400005e450000 4E5500005E550000.
