missing = Where(data EQ -999.99, count)
IF count GT 0 THEN data[missing] = !Values.F_NAN
scaledData = BytScl(data, Top=253, /NAN)
LoadCT, 33, NColors=254
TVLCT, FSC_Color('white', /Triple), 254
IF count GT 0 THEN scaledData[missing] = 254
TVImage, data

Cheers,

David

P.S. I'll put you down for a copy from the first printing
run. :-)
