You can use theSYMPUT routineto create a macro variable and to assign to that variable any value that is available in the DATA step. When you use the SYMPUT routine to create a macro variable in a DATA step, the

create macro: %let = 一些auto存好的: macro character function 作用在macro variable上 常见的function如: index直接从1开始 (区别于python index) 5. 总结: 建立macro variable的三种方法 (i) %let = (定义) %put = (return macro variable) (ii). 在 DATA step 创建macro variable: call symputx('va...
The SAS® Data step/Macro InterfaceThe SAS(R) macro facility is an extremely useful part of the SAS(R) System. However, macro variables and the macros themselves do not have to be exclusively referenced from within the macro facility. The SAS(R) data step can create, resolve and execute...
• Create the macro variablein open code. • List the macro variable on a%GLOBAL(default value is null) statement in the macro programin which it is defined. • Create the macro variablein aDATA stepwithCALL SYMPUTXwhen the global symbol table is specified. ...

it will select data for the correct month and print the correct title. This is time-consuming and prone to errors.You canuse %LET to create a macro variable.Then you can change the value of the macro variable in the%LET statement,and SAS will repeat the new value throughout your ...
Technically you can use %<macro name>; and &<macro variable> much like you can anywhere else, though if you don't know what you are doing you will just create problems for yourself. If you provide exmaples of your input data (datastep), and what you want to do I can show how ...

用宏(macro)来管理你的代码。打开MAUTOSOURCE系统选项以便自动调用宏(这是默认的)。 13.Create macro libraries to store common macro routines in one place. 在同一个地方建库,存放所有类似的宏文件。 14.Create permanent libraries containing information from dai...
