再问有关字符型变量长度问题

shiyiming

PROC CONTENTS DATA=NEW OUT=AA(KEEP=NAME);
RUN;

PROC SQL;
      SELECT NAME
          INTO: VARNAME SEPERATE BY ' '
          FROM AA;
QUIT;

DATA BB;
     DO I=1 TO 169;
            B=SCAN("&VARNAME",I,' ');
            OUTPUT;
         END;
RUN;
经上面的程序出现下面的WARNING：
The quoted string currently being processed has become more than 262 characters long.  You may have unbalanced quotation marks.
有人能解释一下262的原因吗？

注：NEW表中有169个变量，每个变量名大约10个字符左右

[code:1ktczp68]options noquotelenmax;[/code:1ktczp68]

真是什么都知道啊。

在默认情况下SAS对于' '之间有262个字符的限制，2楼的是高手啊，这个option偶不晓得
