错误：在需要数字操作数的 %EVAL 函数或 %IF 条件中找到字符操作数

Question

我遇到以下错误。

错误：在需要数字操作数的 %EVAL 函数或 %IF 条件中找到字符操作数。条件是：&N_GROUP

错误：%DO I 循环的 %TO 值无效。

错误：宏 ORDERFLOW 将停止执行。

当我在没有远程提交的情况下在本地测试它时，它起作用了。但它不适用于 WRDS 服务器。我尝试了很多方法来解决此问题，但无法找出问题所在。

这是我的代码。仅供参考，这是一个更大的试验代码。

%macro orderflow(YYYYMMDD=, CUTOFF=) /des = "Create OrderFlow"; 

%syslput YYYYMMDD = &YYYYMMDD;
%syslput CUTOFF = &CUTOFF;

%let wrds = wrds.wharton.upenn.edu 4016;
options comamid=TCP;
signon wrds username=_prompt_;

rsubmit;

/* Enter your WRDS institution name and your WRDS username */
options errors=2;

    /* Create StockList each having 100 stocks */
    proc sql noprint;
    select  ceil(count(SYMBOL_ROOT)/&CUTOFF)    into :N_GROUP     
    from  mast.mastm_&YYYYMMDD

    and  TAPE = 'A'                         /* Common stock */     
    ; quit;
    
    %do i=1 %to &N_GROUP;
        %global STOCKLIST&i;
        proc sql noprint;

感谢任何 cmets。谢谢。

此宏被构造为在 LOCAL 机器上运行，因为它包含 SIGNON 和 RSUBMIT/ENDRSUBMIT 块。

但是您正在引用通过 SQL INTO 子句在远程计算机上创建的宏变量 N_GROUP。我认为这是错误消息的原因。

要么定义要在远程机器上运行的宏，要么使用%SYSRPUT 将宏变量值移回本地机器，以便您可以使用它来控制%DO 循环。
