I've got a nasty bit of sql using a union to provide a header line. SQL*Plus likes to place a blank line between the output of the unions and I want to get rid of it. I've done it before, but I have forgotten. I do recall that we never found documentation on it and 'stumbled' across the solution.
The sql is below

TIA,
Dan Fink
