Syntax

-MSYMTABMAX n | nK | nM | nG |nT | hexX | MIN | MAX

MSYMTABMAX=n | nK | nM | nG | nT |hexX | MIN | MAX

n | nK | nM | nG | nT: specifies the amount of memory that is available in multiples of 1; 1,024 (kilobytes); 1,048,576 (megabytes); 1,072,741,824 (gigabytes); and 1,099,511,627,776 (terabytes), respectively. You can specify decimal values for the number of kilobytes, megabytes, gigabytes, or terabytes. 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 that is available 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 amount of memory to 45 bytes.
MIN: sets the amount of memory that is available to the minimum setting, which is 0. This value causes all macro variables to be written to disk.
MAX: sets the amount of memory that is available to the maximum setting.

After the MSYMTABMAX value is reached, SAS writes any additional macro variables to disk.
