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...
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...
DATA 步语句是出现在 DATA 步中的可执行(Executable)或声明性(Declarative)语句。可执行语句会在DATA 步的各个迭代中执行某些操作;声明性语句则向SAS系统提供信息,并在系统编译程序语句时生效。 以下展示了一些在DATA步中用到的执行语句和声明性语句。...
Examples 7、LOWCASE(X) Converts all letters in an argument to lowercase. 将变量中所有字母转换成小写 Details In a DATA step, if the LOWCASE function returns a value to a variable that has not previously been assigned a length, then that variable is giv...
