Not quite sure here what you mean by "I am using 'x.'" etc. Also, is that 
boolean expression quite right, or do you mean IF Str.Match() ?

What functions are you using to write and read the file? In general, they 
won't know about your data representation, so it's down to you to check 
for EOF etc.

Hope that's been of some help
