Question

我为我所在公司的团队建立/建立了一个流程。但是，每当我运行部分代码时，我都会看到这个注释。 SAS似乎是将我的角色值转换为数字并且它的错误。它似乎没有引起我的数据明显的问题...但我想知道为什么，如果可以的话，解决这个问题。这是我日志中的代码片段：

MPRINT(CFPB):   DATA trunc;
MPRINT(CFPB):   SET eq_final;
MPRINT(CFPB):   Acct_Num=SUBSTR(Acct_Numb,7,4);
MPRINT(CFPB):   Source = "Eq";
MPRINT(CFPB):   IF Acct_Type = "1" or "01" THEN Acct_Description = "Unsecured";
MPRINT(CFPB):   IF Acct_Type = "0" or "00" THEN Acct_Description = "AutoOnly";
MPRINT(CFPB):   IF Acct_Type = "2" or "02" THEN Acct_Description = "AutoOther";
MPRINT(CFPB):   IF Acct_Type = "6D" THEN Acct_Description = "HELON";
MPRINT(CFPB):   IF Acct_Type = "89" THEN Acct_Description = "HELOC";
MPRINT(CFPB):   IF Acct_Type = "0G" THEN Acct_Description = "FlexSpending";
MPRINT(CFPB):   IF Acct_Type = "18" THEN Acct_Description = "CrCard";
MPRINT(CFPB):   IF inputAssocCode not =: "W" AND Error_Description not =: "A1/J1" OR "A2/J2";
MPRINT(CFPB):   IF Error_Description not =: "No Error";
MPRINT(CFPB):   DROP Acct_Numb ;
MPRINT(CFPB):   RUN;

我怀疑问题出在您的代码的这一部分和其他类似的部分：

 IF Acct_Type = "1" or "01" then ...
 IF inputAssocCode not =: "W" AND Error_Description not =: "A1/J1" OR "A2/J2";

由于SAS运算符优先级，这等同于：

 IF (Acct_Type = "1") or "01" then ...
 IF inputAssocCode not =: "W" AND Error_Description (not =: "A1/J1") OR "A2/J2";

SAS将尝试将字符文字“01”和“A2 / J2”解释为逻辑值，因为它们被用在or运算符旁边，这涉及首先将它们转换为数字。

您应该使用in运算符，例如

 IF Acct_Type in ("1","01") then ...
 IF inputAssocCode ne: "W" AND not (Error_Description in: ("A1/J1","A2/J2"));

为什么SAS将字符转换为数字？
