It makes more sense to me that (FILE,FILE) is kind of the same thing as
saying (@a,@b). In list context @a returns the array as a list, but in
scalar context @a returns the number of elements.

John,
I am a lotus user so my top-down reply is default ...sorry.
Don't know Lotus. No possibilities to change defaults there? ;-)
I think all looks good, but I have to ask why are you initializing an array
to hold values of a hash

* If the format of all your data lines is consistent, you could use
split
on \s+ to get the data fields instead of a tr/m cascade.
* Then, if I understand you correctly, you wantto build a hash with %
keys
and F... values. This could be done with code like
push @{$lookup_hash{$pct_value}},

I was thinking of using a hash of arrays b/c I want to look-up each array
by a certain string and that string would the % string.
My goal is to populate a hash of some sort with the % string and its
associated F string.
Here is the data file:

Hello all,
I'm obviously making a silly mistake here and would appreciate it if
someone can point out my error. I am trying to populate a hash of a
hash in a while() loop. Here is what I have:

I am not populating from a file, actually. I'm populating from the
output of $sth-fetch from DBI. The $something and $something_else
variables in this case are numbers which have been defined by the output
of that method.
If I do $hash{SOMETHING}{0} = $something;
Then my hash is populated
If I do $hash{SOMETHING}{0} = $something;
Then my hash is populated correctly. I am only not getting
results if I
do $hash{SOMETHING}{$i} = $something. The key here is how I am using
the variable $i in my hash.
I tried this on my machine and it worked fine:
