n | nK
| nM | nG
-
specifies the amount of memory to reserve
in multiples of 1 (bytes); 1,024 (kilobytes); 1,048,576 (megabytes); or 1,073,741,824
(gigabytes), respectively. The value of n can
be a decimal value. 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 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 a value of 0, which indicates
that the memory usage is determined by SAS when SAS starts. This is the default
value and should not be changed under normal conditions.
-
MAX
-
specifies to set the memory size to the
largest permissible value.
Use the REALMEMSIZE= system option to
optimize the performance of SAS procedures that alter their algorithms and
memory usage. Setting the value of REALMEMSIZE= too low might result in less
than optimal performance.
