specifies the amount of memory in multiples
of 1 (bytes); 1,024 (kilobytes); 1,048,576 (megabytes); or 1,073,741,824
(gigabytes). You can specify decimal values for the number of kilobytes, megabytes,
or gigabytes. For example, a value of 8
specifies 8 bytes, a value of .782k
specifies 801 bytes, and a value of 3m
specifies 3,145,728 bytes.
If n=0,
the sort utility
uses its default.
-
hexX
-
specifies the amount of memory as a hexadecimal
value. You must specify the value beginning with a number (0-9), followed
by hexadecimal characters (0-9, A-F), and then followed by an X. For
example, the value 2dx
sets the amount of memory to 45 bytes.
-
MIN
-
specifies the minimum amount of memory available.
-
MAX
-
depends on the sort utility. For the SAS
sort utility, MAX specifies the maximum amount of memory available. For the
host sort utility, MAX specifies an amount that is based on the size of the
input file. For more information about how these values are determined, contact
SAS Technical Support.
Generally, the value of the SORTSIZE=
system option should be less than the physical memory available to your process.
If the SORT procedure needs more memory than you specify, the system creates
a temporary utility file.
For OpenVMS, the default value for SORTSIZE is MAX.
Note: Proper specification of SORTSIZE= can improve
sort performance by restricting the swapping of memory that is controlled
by the operating
environment. ![[cautionend]](../../../../common/63294/HTML/default/images/cautend.gif)
