Specifies the maximum amount of memory available to the macro variable symbol tables.

Default:	4M (set in the installed !SASROOT/sasv9.cfg file)
Valid in:	configuration file, SAS invocation, OPTIONS statement, SAS System Options window, SASV9_OPTIONS environment variable
Category:	Macro: SAS macro
PROC OPTIONS GROUP=	MACRO
UNIX specifics:	default value

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

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

n | nK | nM | nG: specifies the maximum amount of memory that is available in multiples of 1 (bytes); 1,024 (kilobytes); 1,048,576 (megabytes); or 1,073,741,824 (gigabytes). You can specify decimal values for the number of kilobytes, megabytes, or gigabytes. 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 maximum amount of memory that is available as a hexadecimal value. You must specify the value beginning with a number (0-9), followed by hexadecimal characters (0-9, A-F), and then followed by an X. For example, 2dx sets the maximum amount of memory to 45 bytes.
MIN: sets the amount of memory that is available to the minimum setting, which is 0 bytes. Setting the amount of memory to the minimum setting causes all macro symbol tables to be written to disk.
MAX: sets the amount of memory that is available to the maximum setting. On 64-bit computers, this value is 9,007,199,254,740,992 bytes.
