Paul,

I had a chat about this to a colleague and they knocked up the following
code.  It seems to do the trick under SAS v6.10 under MS/Windows.  For other
operating systems you may need to make some modifications (e.g. The check for
form feed is ASCII 13, I don't know what value a form feed has under (e.g.)
EBCDIC).  I suspect that you are running SAS under UNIX; in which case just
change the file locations.

The code follows, good luck ....
