You can use the GETOPTION function to query for the current value of an option. And if you wrap the call the GETOPTION function with the %SYSFUNC macro, you can save the value in a macro variable to it can be easily restored. For example, the following will enable you to use NOCENTER NONUMBER NODATE for some output and then reset the values back to their original values:

%let saveOptions = 
       %sysfunc(getoption(CENTER)) %sysfunc(getoption(NUMBER)) %sysfunc(getoption(DATE));
options nocenter nonumber nodate;

/* your code that depends on these options */

options &saveOptions; /* reset options to original values */
