Hi David!
Thanks for the reply but the output given by the above code again
only produces a single column instead of multiple columns.  instead of
given
1
2
3
white space
3.05
4
5
whitespace
-6.3
7

Produce an output such that:
1,-3.05,-6.3
2,4,7
3,5

Please If you don't mind i can send you my actual input file off the 
list to try with. my email is georgkam hosted with the google email 
domain
