当链接到电子邮件发送的条件无法执行时,为什么这段代码仍然发送电子邮件?SASLOG 证明条件值为零,即 x=。

100 data _null_;
/* Set variable */
101 x=0;
102 put x=;
/* condition cannot be true */
103 if x=1 then do;
104 link send_email; /* should only be hit if condition is true */
105 end;
106 return;
107
108 send_email: /* seems to get executed no matter what */

112 put "Email test from SAS program";
113 put " ";
