In this example, you invoke SAS on a UNIX operating environment on September 20, 2001 (the librefs DEPT and TEST are defined in the config.sas file) with a command like the following:sas program-name -sysparm dept.projects -config /myid/config.sasMacro variable SYSPARM supplies the name ...
打开MACROLIB逻辑库,可以看到编译后的宏程序存储在MACROLIB.SASMACR中。 利用以上方式存储有一个缺点,就是需要备份宏程序的源代码,因为存储的是编译后的宏,并不能从编译的宏得到源代码。如果后期对源代码升级优化后,需要重新编译存储。 除了备份源代码,也可以在%MACRO语句中增加一个SOURCE选项,使其在存储编译宏的...

多项式模型,泰勒多项式,SAS MACRO Polynomial ModelTaylor’s PolynomialSAS MACRO本篇论文是希望藉助SAS MACRO程序,提出一个能解决建立多项式模型上的困恼.多项式模型在统计分析上一直是被忽略的,这可以很清楚的知道因为在所有的统计分析的出版品中很难找到以多项式回归为主提的例子.这原因无非是无法解决大量变量的模型...
那么将回归程序写成一个宏,每次用的时候换参数就可以了。 总之,宏可以降低重复性工作的任务量,使程序...
解答: ? 使用Macro变量. 创建和使用用户定义的macro 变量 ? 用 %LET定义变量. ? 然后用 variable 指示变量(C的指针?). ? Macro 把 variable 变换成值. 语法: %LET variable=value; %LET NAME=PAYROLL; DATA NAME; INPUT EMP$ RATE; DATALINES; TOM 10 JIM 10 ; PROC PRINT DATA=NAME; TITLE PRINT ...
One way in which macro language is different from SAS language isMacro-variable values are always text, quotation marks are not needed to indicate texr constants in the macro language. EXAMPLE dsid=open("sasuser.houses","i"); /*has quotation marks, because it's a DATA step function*/ ...
Using all capital-letters for built-in SAS functions and designations and all lower-case letters for variable names can help distinguish the two.使用所有大写字母的内置SAS函数和指定和所有小写字母的变量名称可以帮助区分两者。 Example 3.11 – Use of c...
