Syntax
MEMSIZE=n | n K|n M|n G|hexX | MIN | MAX
System Options under z/OS MEMSIZE= System Option 479
n | n K|n M|n G
specifies total memory size in bytes (0–2,147,483,647), kilobytes (0–2,097,151),
megabytes (0–2047), or gigabytes (0–2). You can specify decimal values for the
number of kilobytes, megabytes, or gigabytes. For example, to specify 33,554,432
bytes, you can use 32M, 32768K, or 33554432.
hexX
specifies the memory size as a hexadecimal value. You must specify the value
beginning with a number (0–9), followed by hex digits (0–9, A–F), and then followed
by an X. For example, the value 2000000x sets the memory size to 32M and a value
of 4000000x sets the memory size to 64M.
MIN
causes SAS to calculate the value of MEMSIZE= using the formula in the following
Details section.
MAX
causes SAS to calculate the value of MEMSIZE= using the formula in the following
Details section.
Details
SAS calculates the value of the MEMSIZE= system option using the formula below if
any of the following are true:
3 No value is specified for MEMSIZE=.
3 A value of 0 is specified for MEMSIZE=.
3 MIN or MAX is specified for MEMSIZE=.
3 The value specified for MEMSIZE= exceeds the size of the user’s currently
available REGION.
