Yeah I tried this originally, and it didn't work. Tried it again as I
may of made a mistake the first time, and it works with no problems
(obviously I had done something stupid again).
Thanks very much,
Lloyd

Read the header as a string array, not as a float array.
Later, if you need numbers out of the header, use READS
to read them from your string array.
