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 ...
SAS在执行阶段之前并不知道数据的具体值是什么,而知道的时候又通常太晚了。 CALL SYMPUT可以使鱼与熊掌兼得。 赋值单个宏变量的一般形式: CALL SYMPUT ("macro-variable", value); 在引号中的macro-variable可以是新创建的,也可以是已有的;value是要赋给宏变量的值,可以是变量名,也可以是引号内的常量。 CALL ...
(or in 是logical operator) 1)忽略logical operator 2)忽略& 6.%SYSGETMacro Function Returns the character string that is the value of the environment variable passed as the argument. The SAS_EXECFILEPATH and SAS_EXECFILENAME environment variables are useful when they are used to obtain the file...
Be careful.You cannot create a macro variable with CALL SYMPUT and use it in the same DATA step.Here’s why. When you submit macro code, it isresolvedby the macro processor, and thencompiledandexecuted.Not until the final stage— execution—does SAS see your data.CALL SYMPUT takes a data...
We may derive new variables in these analysis data sets. Metadata attributes such as data set labels, variable labels and formats are important and useful to users. Specific metadata attributes are often required as an industry standard, such as the CDISC Study Data Tabulation Model (SDTM), for...
%put &Sqlobs Names added to Macro variable (array) %nrstr(&NAMES) ; 这里第二行的names宏变量就是包含了SASHelp.class表中的全部name的值,并且以" "分隔开。 为了演示SCAN与%SCAN的区别,我们看一看下面两个例子: data _null_; test="AA...
When the autocomplete option is enabled, SAS Enterprise Guide might unexpectedly stop working when you enter the dot (.) for a macro variable in your code. For example, the problem might occur when you enter &macvar. as shown in the following sample code: %macro ChangedPct(macvar); data...

I know with a character variable in SAS, you want to define the length first otherwise it'll have the length of the first value. I wonder if this is something that'll affect macro vars as well? I'm just talking about normal variables like a counter in a do loop. I'm ...
