hello
Say I am interested in users giving me values for a, b, c and d.
I have a file with all the results - a very big file!
user 1
a: one
b: two
d: four
user 2
a: one
b: two
c: three
d: four
etc etc
and want to create a file
user a b c d
1 one two x four
2 one two three four
etc etc
How do I put in an x for c for user 1, indicating that this user
didn't submit a value for c?
I slurping the way to do it?
Cheers
Geoff

No need for slurping in the whole file. If you know the set of all a, b,
c, d, ... in advance then just go ahead and create the top row. Then
read in the information for each user and print the row for him.
If you don't know the set of all a, b, c, ... in advance then read the
file twice: first pass just to determine the set of a, b, c, ... and the
second pass as above.
