求大神解答。

试试这个
proc iml symsize=n1 worksize=n2;
*  n1 and n2 are specified in kilobytes.
*  The WORKSIZE= and SYMSIZE= options offer tools for tuning memory usage. For data-intensive applications that involve a few large matrices, use a high WORKSIZE= value and a low SYMSIZE= value. For symbol-intensive applications that involve many matrices, perhaps through the use of many IML modules, use a high SYMSIZE= value.
* You can use the SHOW SPACE command to display the current status of IML memory usage. This command also lists the total number of compressions done on all extents.

谢谢大神，我试了这个，可是不管用啊。我用show space的时候，会显示固定是多少kb
