摘自123题中第66题

66. The following SAS program is submitted:

libname sasdata 'SAS-data-library';

data test;

set sasdata.chemists (keep = job_code);

if job_code = 'chem3'

then description = 'Senior Chemist';

run;

The variable JOB_CODE is a character variable with a length of 6 bytes.

Which one of the following is the length of the variable DESCRIPTION in the output data set?

A. 6 bytes

B. 8 bytes

C. 14 bytes

D. 200 bytes

答案：C

这里的14是数字符数出来的吗，可是bytes 变量的储存长度等于数出来的字符长度吗？

对于判断length晕晕乎乎的，希望大神能讲讲相关知识点

不胜感激
