我们有一组在SAS中开发的预定义宏,可用于使用SAS数据集生成表,列表和图形。我的要求是专门为表自动生成SAS代码。有一些固定数量的模板可用于生成表。此外,还可以使用SAS程序来生成每个表的输出。每当需要从这些模板生成表时,都需要修改相关的SAS程序以生成所需的输出。
为避免每次分别编写SAS程序来生成固定类型的输出的冗余,我想创建一个将生成SAS代码的工具。此代码将用作生成表的源。
我准备了一个excel工作簿,其中包含构建程序所需的所有详细信息(例如各种参数及其值,例如标题,脚注,源数据集,按行/列分组)。在Excel中创建的简单用户表单用于显示和配置这些参数。
现在的问题是-如何使用Excel VBA生成SAS语句?以及如何使用Excel VBA与SAS连接以执行SAS程序?
如果您之前已经做过类似的事情,或者对这种类型的问题陈述有任何想法,请在这里分享。任何帮助都是非常有意义的。
谢谢。

我不会涉及VBA。我将编写一个SAS程序来读取需求,生成表并将它们推回到新的Excel程序中。如果您想从Excel程序中完全驱动它,我建议您使用Excel的SAS加载项而不是VBA代码,尽管您可以通过VBA触发它。克里斯·海米丁格(Chris Hemidinger)是这类问题的SAS专家,他确实在community.sas.com上发帖,因为另一个用户指示您应该在此处发帖(以评论形式)。
创建空表是一个微不足道的过程,但是报表表通常具有非常特定的布局,因此您可以进一步概括该过程。例如,我有一个宏可以为数据集创建我的标准表1(特性表),在这里我只需要按类型(连续,分类,二进制)指定输入变量,就可以生成输出并将其推送通过ODS EXCEL脱颖而出。我还使用PROC REPORT对其进行格式化,因为我将为不同的变量交替地对行进行阴影处理,以便于阅读/显示。
