Even more pernicious, sometimes those empty lines will have
space characters on them. Aaauuuggghhh! Try doing a string
compress on the string array before checking for empty
strings.

file = 'datafile.dat'
rows = File_Lines(file)
data = StrArr(rows OpenR, lun, file, /Get_Lun
ReadF, lun, data
Free_lun, lun
data = StrCompress(data, /REMOVE_ALL)
I = Where( data EQ "", count)
IF count GT 0 THEN Print, "I got trouble!!"

Cheers,

David
