1).Automatic Macro Variables:可以理解为系统宏变量或者自动宏变量 例如sysdate 2).user-defined macro variables 3.按作用域分为两类: Automatic Macro Variables都是全局宏,在macro外定义的也是global micro variable,在macro内定义的是本地宏变量的。(宏变量的作用域不涉及文件(%include问题),数据集或者proc步。...
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 SYMPUT routine or SYMPUTX routine executes,it will create a global macro variable. 依据变量...
• 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. • Define a global macro ...
宏变量包含两种:local和global。 局部宏变量:A macro variable’s scope is local if it is defined inside a macro. 全局宏变量:Its scope is global if it is defined in “open code” which is everything outside a macro. 使用范围: You can use aglobal macrovariable anywhere in your program, bu...
Re: create macro variable from data field Posted 09-05-2024 11:35 PM (6003 views) | In reply to dwaldo There is a data step way: data _null_; set have end=end_of_have; length value $10 freq 8; if _n_=1 then do; declare hash h (ordered:'a'); h.definekey('value');...

2.Associate compatible data with the template using theSGRENDERprocedure to create the graph. SGRENDER语法: 注意: Variable namescan be hard-coded in the template, such as “Height”, “Weight”, or “Age”, as in the SASHELP.CLASS data set. TheSGRENDERprocedure will validate thatvariable name...
