sas - 如何发现是否设置了 SAS 选项或 ODS 选项

Question

我经常在 SAS 中编写通用宏。在我的宏中，我想应用一些设置，比如

• 宏变量
• SAS 选项
• ODS 选项

但事后我想“收拾残局”。

对于将是的宏变量

%macro myMac();
    %let old_mac_var = &mac_var;

    %let mac_var = my_variable;
    %put Doing my stuf with &mac_var.;

    %let mac_var = &old_mac_var;
%mend;

%let mac_var = value before;
%myMac;
%put mac_var is &mac_var;

(当然我会在实践中使用局部宏变量来解决这个问题，但这不相关。)

但是对于其他设置我该如何做呢？即我如何完成此代码？

%macro test_mprint(should_shouldNot);
    data _null_;
        put "NOTE: 'data _null_;' &should_shouldNot. be readable here above in the log";
    run;
%mend;

%macro myMac();
    %let sas_mprint = ...;
    %let ods_exclude = ...;

    options nomprint;
    ods exclude none;

    title 'CARS should be printed because of ods option exclude none';
    proc print data=sashelp.class;
    run;
    %test_mprint(should not);

    options &sas_mprint.;
    ods exclude &ods_exclude.;
%mend;

options mprint;
ods exclude all;
%myMac;

title 'printing CLASS should be avoided by ods option exclude all';
proc print data=sashelp.class;
run;
%test_mprint(should);

Answer 1

SAS 选项很容易检索:

%let sas_mprint = %sysfunc(getoption(mprint));  /* gives, eg, NOMPRINT */

ODS 选项不太确定..
