求教！哪位大神给我讲解一下这一串代码是什么意思？新手上路，很着急！！！！！！！

treenode thelist = getvarnode(current,"componentlist");
  treenode thesum = getvarnode(current,"targetcomponentsum");
  setnodenum(thesum,0);
% I7 o$ ~% \5 N& U  s# H1 h
   {
1 @! a& W9 k2 u0 i     setnodenum(cellrowcolumn(thelist,1,1),getlabelnum(first(current),"1"));
    inc(thesum,getlabelnum(first(current),"1"));
     setnodenum(cellrowcolumn(thelist,2,1),getlabelnum(first(current),"2"));
0 }" x# N- g* c& Z% A0 i    inc(thesum,getlabelnum(first(current),"2"));
     setnodenum(cellrowcolumn(thelist,3,1),getlabelnum(first(current),"3"));
    inc(thesum,getlabelnum(first(current),"3"));
     setnodenum(cellrowcolumn(thelist,4,1),getlabelnum(first(current),"4"));
    inc(thesum,getlabelnum(first(current),"4"));
  }
' U2 \% S, r& E' i# m}

你的代码不全啊，但是大概就是根据当前实体的标签值设置属性节点“componentlist”（好像是个表格）的值，，然后将节点targetcomponentsum的值加対应标签的值。

我这新手，主要是不明白  setnodenum 、getlabelnum这之类的具体什么含义，有什么作用
