Weird. On *every* endif?

Such basic syntax error reports are an indication code is definitely not "solid". Now,
don't take that the wrong way: most of my code qualifies in the jello category so I'm
quite familiar with the phenomenon. :o)

Apart from the strangeness of "where(XX ne XX)", what happens if you replace

if ((where(XX ne XX))(0) ne -1) then begin

with

if ((where(XX ne XX))[0] ne -1) then begin

?

cheers,
