A simple test would be to read all the lines in your file
as a string array, and then see if any of the strings were
blank:

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

Cheers,

David
