SUMSIZE=n | nK | nM | nG | MIN | MAX | hex

Syntax Description

n | nK | nM | nG: specifies the amount of memory in bytes, kilobytes, megabytes, and gigabytes, respectively. When n=0, the default value, 8M, is used.
MIN: specifies the minimum amount of memory available.
MAX: specifies the maximum amount of memory available.
hex: specifies the amount of memory as a hexadecimal number. This number must be followed by an X.

Details

The SUMSIZE= system option affects the MEANS, SUMMARY, TABULATE, and SURVEYMEANS procedures.

Generally, the value of the SUMSIZE= system option should be less than the physical memory available to your process. If the procedure you are using needs more memory than you specify, the system creates a temporary utility file.

PERFORMANCE NOTE: Proper specification of SUMSIZE= can improve procedure performance by restricting the swapping of memory controlled by the operating environment.
