Introduction SAS 内置 debug 工具,可以用于 debug DATA step. 通过在 DATA 步中加上相应的 debug 命令,并运行DATA步,就可以调出 Debugger 查看每一行代码的运行结果。 参考DATA Step Debugger: Examples - 9.2 (sas.com) Usage and Example 首先在 data step 中添加 /debug 命令: /*This is the raw code*/...
The SAS do loop is the simplest form of the do loop, which can be executed within the SAS data step. The actions are iterated at the do loop conditional and unconditional execution. It has n number of times for data processing execution and provided the most straightforward way for data ap...
We all know the SAS Data Step is a very flexible and powerful tool for data processing. In fact, the Data Step is very useful in the creation of a non-trivial BDS dataset. This paper walks through a series of examples showing use of the SAS DATA STEP when deriving rows in BDS. ...
Examples are provided todemonstrate the pitfalls one can experience when constructing a data step. Being cautious can avoid unexpected results. This paper uses a PUT _ALL_ statement to demonstrate how automatic retain variables can be retained.Huei-Ling Chen...
