将sas宏变量作为参数传递给VB脚本

Question

下面是用于进行预测然后创建excel输出的SAS代码，一旦输出存储在excel文件中，我调用VBA宏来为每个excel文件和每张工作簿生成一个图表

在SAS宏中我已经为我的excel文件定义了一个输出路径，我希望在VBA宏中使用相同的路径而不使其成为固定值，所以如果我运行这个sas代码以获得不同位置的输出我的VBA从sas宏变量中获取该路径。

Answer 1

我在创建DOS脚本时遇到了同样的问题，我提出的解决方案（可能适用于此处）是使用编码到脚本中的参数创建脚本，只需调用脚本本身。

希望有所帮助。

Answer 2

我会在方法上做一些改变。我会创建一个接受命令行参数的独立VBScript，而不是使用VBA宏来制作电子表格。由于VBS和VBA具有显着的重叠，因此语法基本相同。 VBS命令行参数是从0开始的位置和索引，并被引用为WScript.Arguments(0)等。然后在您的SAS程序中，只需在创建输出文件后执行此操作：

options xsync noxwait;

data _null_;
    shell = 'C:\Windows\SysWOW64\cscript.exe';
    script = '"C:\Path-to-your-VBS\script.vbs"';
    args = "&macrovar";
    call system(catx(' ', shell, script, args));
run;

xsync选项告诉SAS在继续执行程序之前等待VBScript完成。 noxwait选项告诉SAS在不提示您的情况下运行命令行垃圾。

如果你有64位操作系统和32位Microsoft Office（和我一样），你可能需要使用C:\Windows\SysWOW64\cscript.exe而不是默认的cscript.exe来运行VBS。

我倾向于避免使用SAS的DDE。我个人认为这是一种更清洁的方法。这也消除了对支持宏的Excel工作簿的需要，因为格式化是通过VBScript在Excel之外完成的。
