Therefore, the first step in writing a macro application is to turn on the debugging options. This paper is intended for programmers at all levels who write macro code, and it concentrates primarily on three SAS system options that you can use to debug macros: MLOGIC,SYMBOLGEN, and MPRINT ...
System Options for macro debugging: 在执行 macro 前面添加 options 帮助输出 macro 执行的一些信息。常用的 options :粗体是选项的默认设置。 /*Usage*/ OPTIONSMPRINT NOSYMBOLGEN NOMLOGIC; /*Options MPRINT*/%macromktitle(proc,data);title"%upcase(&proc)of%upcase(&data)";%mendmktitle;optionsmprint;...
原因是在数据步时,当出现*时,SAS编译器就得到一个KEYWORD,告诉编译器这个星号直到下一个分号;之间的内容都是注释。但是在SAS宏代码时,由于SAS宏编译器并不将星号*当作是一个KEYWORD,因此,*只是一个token(详见SAS宏编译原理),这时,其后面的代码将不...
It would help (now, and 100% of the time in the future) for you to show us the ENTIRE log for this macro. Please first turn on macro debugging options by running this command: options mprint symbolgen; Then, run the macro again, copy the ENTIRE log as text, and paste ...
Examples: IF &TOTAL > 999 THEN WEIGHT=WEIGHT+1; &CHAR = %LENGTH(&SPAN) &COUNT = %EVAL(&COUNT + 1); 3 Tip #1 – Debugging a Macro with SAS System Options The SAS System offers users a number of useful system options to help debug macro issues and problems. The results associated ...
Start with working SAS code, then replace the necessary parts with macro variables to make it dynamic. Use options mprint mlogic symbolgen; when debugging macro code, and (Maxim 2) read the log. In its entirety. Maxims of Maximally Efficient SAS ProgrammersHow to convert datasets to data step...

This debugging facility makes it easy to 1ral:e the execution ofone or more SAS macros within a SAS job. You can control printing start- and end-banners that identify nw:ros, including revision date and support group; checking the values of macro parameters; printing notes following PROC ...
