How to change all derived variables to upper case?

/*************************************************************************
*If you ever need to change the derived variables name from lower case to
upper case, there is a SAS option that you can use to take care of that
instead of retyping them one by one.  Here's the option:

options validvarname=upcase;

Rest.sas to set correct formchar for PC/Windows Format

This was quite useful before the ODS was introduced.

Create a calendar using SAS PROC REPORT

This collection is from SAS website at http://support.sas.com/kb/50/099.html

The sample code below contains two sections. The top section creates a calendar that contains only the dates. The bottom section creates a calendar that includes text within date cells.
