Thanks,
I did not know that one could do this and get away with it. Believed
one had to set the delimiter first and since it is varying number of
spaces it would not work.
But it seems like it does work!

I applied your method by removing all the code for handling this and
used only the following:
{code}
   ReadLn(F, sLine);
   slDecode.DelimitedText := sLine;
   ....

{code}

I timed my original code for a file of some 660000+ lines to 9.9s.
Result:
Original code takes 9.9 s to process the file.
Modified code takes 4.4 s

And I checked with the file containing the extra spaces and varying
size of whitespace. It too was processed correctly.

Thanks again!
