n |
nK
-
specifies the maximum macro variable size
in multiples of 1 or 1,024 (kilobytes), respectively. You can specify decimal
values for the number of kilobytes. For example, a value of 8
specifies 8 bytes, a value of .782k
specifies 801 bytes, and a value of 3k
specifies 3,072 bytes.
-
hexX
-
specifies the maximum macro variable size
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 maximum macro variable size to 45
bytes.
-
MIN
-
sets the macro variable size to the minimum
setting, which is 0 bytes. This value causes all macro variables to be written
to disk.
-
MAX
-
sets the macro variable size to the maximum
setting, which is 65,534 bytes.
The MVARSIZE system option specifies the
maximum size for macro variables that are stored in memory. If the size of
the macro variable is larger than the maximum value that is specified, variables
are written out to disk.
The value of the MVARSIZE system option can affect system
performance. Before you specify the value for production jobs, run tests to
determine the optimum value.
