Well heck I did mix the E and B up, thanks for the catch...
 
 
The Reason this doesnt work:
%put %SysFunc( IntnX( 'Month', '01Mar2012'd , 0 , 'E' ) );
 
Is because your working in the macro language and not the data step language.
 
In the data step language words have meaning ( Data Run quit set merge etc...)
so we there for have to specify thos words we dont want interpreted by surounding
the, with quotes.  In the macro language everything is considered not to have meaning
and just text.  Therefore we have to tell SAS which words to interpret as having meaning 
by prefixing with & and %.  
 
Now my guess is the qoutes screw with the macro interface into the data step facility, which 
is what %Sysfunc was designed to do.  Trust me this isnt first nor the only data step function that
%sysfunc screws things up when the function is given qouted values
