Syntax

MVARSIZE= n |nK | nM | nG | MIN | MAX | hex

Syntax Description

n | nK | nM | nG: specifies the maximum size for macro variables stored in memory in terms of bytes, kilobytes, megabytes, and gigabytes, respectively.
MIN: sets MVARSIZE to 0, which causes all macro variables to be written to disk.
MAX: specifies the maximum amount of memory available.
hex: sets the maximum macro variable size stored in memory as a hexadecimal number. This number must be followed by an X.

Details

If the size of the macro variable is larger than the maximum value that is specified, variables are written out to disk.

The value that you specify with the MVARSIZE= system option can range from 0 to the largest positive integer that is representable on your operating environment.

Operating Environment Information: The value of MVARSIZE= can affect system performance. Before you specify the value for production jobs, run tests to determine the optimum value. For further information and default settings, see the SAS documentation for your operating environment. [cautionend]
