如何发现是否设置了 SAS 选项或 ODS 选项

How to discover if a SAS option or ODS option is set

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

但之后我想"clean up my mess"。

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);

SAS 选项很容易检索:

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

ODS 选项不太确定..

我想您会在 this SAS help pageRESET=Push 和 POP 部分中找到相关信息,其中遗憾的是仅适用于 ODS GRAPHICS 选项。
