CALL SYMPUT(”macro-variable-name”,value); macro-variable-name是变量名, value可以是一个变量名,该变量的值将分配给macro-variable-name,也可以是一个用引号括起来的常量。 call symput通常在IF-THEN语句中使用: IF Age>=18 THEN CALL SYMPUT(”status”,”Adult”); ELSE CALL SYMPUT(”status”,”Minor...

之所以产生这样的结果是因为%local实际上在macro内部创建了一个局部宏变量nobs,macro内部访问以及更新操作都是对这个局部宏变量而言的。实际上,macro在执行当中遇到宏变量需要解析的时候,会遵循就近原则,优先解析该作用域内的宏变量,如果该作用域内不存在该宏变量,则向上递归查找该宏变量,直至最外层,如果找不到则在当...

%LET macro-variable-name=value; 宏变量名必须符合SAS命名法则,(少于等于32字节、以字母或下划线开头、只能包括字母、数字和下划线),下面创建了宏变量: %LET iterations=10; %LET country=New Zealand; 当赋值字符串时,不需要加引号。除非开头和结尾的空格,否则从等号到分号的全部内容都是变量值。
CALL SYMPUTX(macro-variable,value<,symbol-table> ); 默认去双尾空白,其他效果和symput一样 随后一个参数表示宏储存的位置'L'=local 'G'=global TheSYMPUTroutine and theSYMPUTXroutinecan only create a local macrovariable if alocal symbol table already exists.If nolocal symbol table exists when the ...

注意到Macro Used这里只写全局性的宏,在这个程序里个人新创建的,只针对这个程序的,不列。对于global macro,其他程序能调用,其他成员也可以调用。 其次,程序里面有大量乱码。 像有些特殊符号,比如写一起的正负号,千分号,大于等于号等等,有的能正常显示,有的不能,这...
