nM
-
specifies the amount of memory reserved in multiples of
1 (bytes); 1,024 (kilobytes); or 1,048,576 (megabytes). You can specify decimal
values for the number of kilobytes or megabytes. 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.
-
MIN
-
specifies the amount of memory reserved
as the minimum value, 0 bytes.
-
hexX
-
specifies the amount of memory reserved
as a hexadecimal number of bytes.
MEMLEAVE= reserves memory in your region that SAS does
not use. A minimum memory reservation is required so that the operating environment
can perform cleanup activities in the event of an abnormal termination of
SAS. You might need to reserve additional memory based on the amount of processing
that is taking place in your region outside of SAS.
The value of MEMLEAVE= has no bearing on the values of the PROCLEAVE=
and SYSLEAVE= system options. MEMLEAVE= reserves memory that is never used
by SAS. This memory is used exclusively by the operating environment. PROCLEAVE=
and SYSLEAVE= reserve SAS memory only.
Setting MEMLEAVE= to 0 is not recommended except for debugging and testing
purposes. The optimal setting depends on the application and the system resources
that are available at your
site.
