Correlating Data from same .csv, line by line

[shadkeene]

Hi,
Here's a complete but minimal example of what I'm doing with a .csv
file (each line in the .csv file corresponds to a certain date).
I'm reading the file and printing out simple statistics for the data
using the grep command. However, I'd like to go a step further and
print the date if a certain thing (or combination of things) occurred
on that day. (i.e. if checkboxes WF and CF were checked...print the
date that they were checked).
My desperate but not functional attempt to correlate the values, line
by line, and place in an array is at the bottom. Thanks for any help!
Shad

open(FH, "C:/perl-scripts/Data/coldseasonworksheet.csv")
or &dienice("couldn't open output file: $!");
seek(FH, 0, SEEK_SET); #goes to beginning of file
my @data = <FH>; #reads file and places in array
close(FH);

my @ETresults = grep(/ET,/, @data);
my $ETnum = @ETresults;

Exiting Troughs this year=$ETnum. <br>

#my @output = (); ###attempt...tried to use "and", "||" so the "||"
would be read first.
#push @output, param('DATE') and param('WF') || param('CF') for
@fields;

That's not a complete example. A complete example is one that I can
copy-an-paste from your posting and execute to reproduce your problem
on my machine. It has to be complete enough to compile with
"use strict; use warnings;" and include any data it needs to run.

The act of reducing the problem down to the point where it can be executed
on another person's computer will often make the error glaringly obvious.
Try it.
