I have to test many base sas code. And each sas code sets some option, create macro varaibles, libname, filename.
Once I test one code then I have to close the base SAS session to reset all option.
Is there any way to reset the session without closing the BASE SAS session.
Closing the SAS session and starting a new one is the easiest and (IMO) best way to achieve that.
Execute your SAS scripts from command line instead and have it output the log/output to external files you can verify at will.
You can use Proc OPTSAVE to save options before a change and then Proc OPTLOAD to restore to the previously saved settings.
You can also use this the approach to store multiple configurations and swithch between them.
If EG is available to you then resetting your session can be as quick and easy as disconnecting your SAS server session then re-connecting. It takes about 3 or 4 mouse clicks and about 5 seconds for me.
