SAS can handle a wide variety of numeric data formats. It uses these formats at the end of the variable names to apply a specific numeric format to the data. SAS use two kinds of numeric formats. One for reading specific formats of the numeric data which is called informat and another ...
<(format-option(s))> :names the format that you are creating(给的格式起一个名字) 名字的限制:A numeric format name can be up to 32 characters in length. A characterformat name can be up to 31 characters in length. If you are creatinga character format, then use a dollar sign (...
4、搭配informats 读取非标准格式的原始数据 ,赋予指定格式 /* character : $informatw., $表示字符串 */ /* numeric:informatw.d,如mmddyy,w是宽度,d是小数点位数 */ /* date:informatw. */ /* eg. input name $10. age 3. height 5.1 birthdate mmddyy10.; */ DATA contest; infile 'D:\RDS...

(either initialized or uninitialized), SAS automatically converts the numeric value to a right-justified character string by using the BEST12. format. In this case, LENGTH returns a value of 12 and writes a note in the SAS log stating that the numeric ...
_NUMERIC_:表示数据集中所有数值变量 这些名称列表在要计算某观测的所有数值变量的均值时(MEAN(OF _NUMERIC_)),或列出某观测所有变量的值时(PUT _ALL_)非常有用。 datazdata.songs;infile"D:\data\sas_file\songs.dat";inputcity $ 1-15 age wj kt tr filp ttr;arraynew (5) song1-song5;/* 数字变...
