SAS default or personalized options are effected when SAS is launched. You can use a simple macro records all important ones for later to recover them back.

Here is an example for ls and ps.


*after launch sas using a macro to store all your original options;
%macro myoption;
    PAGESIZE= %sysfunc(getoption(PAGESIZE))
        LINESIZE= %sysfunc(getoption(LINESIZE))
%mend;
%let default_option=options %myoption;
%put "&default_option";

*****change options****;
options ls=120 ps=5000;

proc options GROUP=LISTCONTROL;
run;

***put default option back;
&default_option;

proc options GROUP=LISTCONTROL;
run;
  

/*Remember the settings of options*/
proc optsave out=opt_save;
run;

/*Change some options*/
options nonumber nodate pagesize=100 nobyline;

/*reset options*/
proc optload data=opt_save;
run;
