report报表显示出错

用proc report产生报表出错，产生的report两边各被截掉了一部分，SAS错误提示如下：
ERROR: Line size too small to place one of the non-ID columns to the right of the ID column(s). ID
column(s) ignored.


请问如何解决，具体些，多谢啦！

proc report data=xxx ls=256;

This error indicates that one of your DEFINEs has too great a width, either explicitly or by default. I suggest checking all the defines and the lengths of character varables. Debugging can be aided by selectively commenting out columns in the column statement in order to narrow down the colunm(s) causing the problem.

对的，ps的选项要设定的

ps——page size
ls——line size
