You can use SYSDAY to check the current day before
executing code that you want to run on certain days of the week, provided
you initialized your SAS session today.
Example: Identifying the Day When a SAS Session Started
The following statement
identifies the day and date when a SAS session started running.
%put This SAS session started running on: &sysday, &sysdate9.;
When this statement
executes on Wednesday, December 19, 2007 for a SAS session that began
executing on Monday, December 17, 2007, the following line is written
to the SAS log:
This SAS session started running on: Monday, 17DEC2007
