George,

I have a utility that I just posted to
http://www.pickwiki.com/cgi-bin/wiki.pl?Row2Col called ROW2COL, which may
help you.

For example:
   CALL ROW2COL(YDATA)     ;* flip the fields and values
   X=SUM(YDATA<2>)
   CALL ROW2COL(YDATA)     ;* flip them back

Or you could set a temporary variable and SUM on it.

Rex
