If memory is critical to your SAS program, SAS provides the following system options to optimize memory usage.
MEMSIZE: This option specifies the total amount of memory that is available to each SAS session.
REALMEMSIZE: This option sets a recommended upper limit on how much real memory your SAS program can allocate. "The REALMEMSIZE option should never be set beyond the amount of real memory. If the amount of real memory is insufficient for a job to run, then setting the MEMSIZE option beyond the real memory might enable the job to run using a combination of real and virtual memory." -- from SAS Web site. See the links below.
SORTSIZE: This option allocates the amount the memory that is available to the SORT procedure.
SUMSIZE: This option specifies a limit on the amount of memory that is available for data summarization procedures.
MVARSIZE: This option specifies the maximum size for in-memory macro variables.
MEXECSIZE: This option specifies the maximum macro size that can be executed in memory.
MSYMTABMAX: This option specifies the maximum amount of memory available to the macro variable symbol table or tables.
