sas编程小技巧集合

1。让SAS支持YYYYMM的日期格式

var1="200206";

date1=input(var1,yymmn6.);

2。proc copy 过程用于libname之间的member复制

3。BLOCK控件没由LABEL属性，但有_setlabel方法，调用如下：

CALL NOTIFY (block-name, '_setLabel', label);

4.proc sort过程的tagsort选型有利于宽数据集的排序

5.

In the following example, DATDIF returns the actual number of days between two dates, and the number of days based on a 30-month and 360-day year.

data _null; sdate='16oct78'd; edate='16feb96'd; actual=datdif(sdate, edate, 'act/act'); days360=datdif(sdate, edate, '30/360'); put actual= days360=; run;

SAS Statements	Results
put actual=;	6332
put days360=;	6240
