Syntax

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

n | nK | nM | nG: specifies the maximum amount of memory that is available for the macro symbol table 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, to specify 1,048,576 bytes, you can use 1M, 1024K, or 1048576.
hexX: specifies the symbol table size 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, the value 0c000x sets the symbol table size to 49,152 and a value of 180000x sets the symbol table size to 1,572,864.
MIN: sets symbol table size to 0 and requires SAS to use the default value.
MAX: sets symbol table size to 2,147,483,647.

The portable default value for MSYMTABMAX is 24,576. Under z/OS, the default value is 1,048,576 bytes.
