for procedures.

specifies the limit in multiples of 1; 1,024
(kilobytes); 1,048,576 (megabytes), and 1,073,741,842 (gigabytes), respectively.
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.
-
hexX
-
specifies the amount of memory as a hexadecimal
value. You must specify the value beginning with a number (0-9), followed
by an X. For example, the value 2dx
sets the amount of memory to 45 bytes.
-
MIN
-
sets the amount of memory to the minimum
setting, which is 0 bytes. This value indicates that there is no limit on
the total amount of memory that can be used by each procedure.
-
MAX
-
sets the amount of memory to the maximum
setting, which is 2,147,483,647 bytes.
Some SAS procedures use the MAXMEMQUERY
option to specify the largest block of virtual memory that SAS can request
at one time. By contrast, the MEMSIZE option places a limit on the total amount
of virtual memory that SAS dynamically allocates at any time. This virtual
memory is supported by a combination of real memory and paging space. The
operating environment begins paging when the amount of virtual memory that
is required exceeds the real memory that is available. To prevent paging and
the associated performance problems, the MAXMEMQUERY and MEMSIZE system options
should be set to a subset of real memory.
