求助sas9.2proc greplay过程

我用的是朱世武编写的《sas编程技术教程》，在运行proc greplay时总是出现错误“ERROR: “IDX399106”不是有效的名称”的情况，请教高手该如何解决呢？谢谢
程序如下所示：
proc greplay nofs  igout=ResDat.graph  gout=ResDat.graph;
tc sashelp.templt;
template l2r2;
treplay 1:idx000001  2:idx000002 3:idx399106  4:idx399001;
run;

Before issuing the TREPLAY statement, specify a graphics input catalog with the IGOUT Statement, assign a template entry catalog with the TC Statement, and choose a template with the TEMPLATE Statement.
