the following SAS program is submitted:

data work.moth;

date=put('13mar2000'd, ddmmyy10.);

run;

which one of the following represents the type and the length of the variable DATE in the output data set?

为什么答案是： character, 10 bytes.

我知道type，哪位大侠给解释一下如何判断 the length of vaiable

thank you very much!  Happy new year!
