in reply to Storing simple Value Pairs

Thanks to all Monks! Lots of interesting possibilities suggested. I guess sometimes I get a bit wrapped around nesting too many perl structs, but I like how many suggestions you've given to how to organize it better. As always I bow to your enlightenment. :)

    Hi, just joined minutes ago. I am trying join tab-delimited files into a single file/table

    Example, say I have these 4 files/tables:

    ID value (table1)

    Aa 22

    Bb 28

    Cc 32

    Dd 50

    ID value (table2)

    Aa 34

    Cc 112

    Dd 77

    Ee 89

    Kk 124

    ID value (table3)

    Bb 75

    Cc 91

    Dd 132

    ID value (table4)

    Aa 66

    Cc 94

    Ee 213

    Gg 250

    The output after joining should look like this:

    ID value1 value2 value3 value4

    Aa 22 34 0 66

    Bb 28 0 75 0

    Cc 32 112 91 94

    Dd 50 77 132 0

    Ee 0 89 0 213

    Gg 0 0 0 250

    Kk 0 124 0 0

    My best effort:

    #usr/bin/perl! use strict; #I opened all files (containg the tables) one by one; is #there a way +I can open all files at once? open(FILEH1, "<table1.txt"); while (my $file = <FILEH1>){ chomp $file; my @file1 = split('\t', $file); #to pick IDs and #values => $fil +e1[0] and $file1[1] } open(FILEH2, "<table2.txt"); #and continued to tables 3 and 4. #And then I tried to collect the items which is where I got #stuck.
      Your post has nothing to do with a reply to the original post (OP).

      I suggest that you start a new question.

      I see that you do understand how to use <code>...</code> tags, so format this critter a bit better.
