如何开始sas从 system prompt?

求助各位大神了

You should be aware of the maximum amount of physical memory your computer has available. Let us assume that doubling the Java memory allocation is feasible. So when you start SAS from a system prompt, you can add the following option:
-jreoptions (-Xmx256m -Xms256m)
Alternatively, you might need to specify the setting in quotation marks:
-jreoptions '(-Xmx256m -Xms256m)'
