If macro-variableexistsin any enclosing scope, macro-variable isupdated.If macro-variable doesnot exist,SYMPUTcreatesit. 注意4:在程序运行阶段,SYSPUT给宏变量赋值。 SYMPUT makes a macro variable assignment when the program executes.
%* Why? because a macro is not allowed to create a macro variable %* in a local scope above its own. %* (It may however, access any macro variables in scope above itself) %* If this macro implicitly 'creates' a macro variable, it will ...

1. Check if the variable already exists 2. If exists, run a plain extract query 3. If not, assign a new variable with that name with "missing" value Now, using the above 3, think how can we translate that into SAS syntax. Gradually, you will build the code. Try 1 Like To...
