请教：proc neural

shiyiming

用SAS过程实现神经网络：（在一个博客中看到下面的一段代码）
proc dmdb data=emnn.standardout out=emnn.dmddata dmdbcat=emnn.dmcdata;
    class z;
    var x y;
run;

proc neural data=emnn.dmddata dmdbcat=emnn.dmcdata graph ranscale=.1 random=0;
   input x / level=int;
   input y / level=int;
   target z/level=nom;

   archi mlp hidden=2;
   prelim 5;
   train;

   score data=emnn.standardout out=pred nodmdb;
   code file='f:\nn.sas';
run;
上面的两个过程dmbc和neural在SAS的help中都搜索不出来，在上面的code中关键字target、archi、prelim……都不被识别

google出来的就两条记录，一条是我我引用的程序的原文，一条是这个帖子
期待答案……
