Um ... you don't, perl does that for you. Hash keys, by definition, are unique. duff	[reply]

Unless I'm missing something, each testcase will have an array of hashes stored at that location. Each testcase will be unique with respect to that. Is this not what you want? thor `Feel the white light, the light within Be your own disciple, fan the sparks of will For all of us waiting, your kingdom will come`	[reply]

Hi thor, right. testcase will be unique. but the array of hashes gets appended again and again. how to maintain uniqueness with the data in the array elements. also one more question here, how to push hashes to each testcase.	[reply]

Well...you are using the `push` function and an array. If you want only one thing to be stored at that location, you'll want something like (untested): `$hoh{$component}{$cmd}{$testcase} = { testsuite_type => $testsuite_type, platform_type => $platform_type, view => $view_type }` [download] thor `Feel the white light, the light within Be your own disciple, fan the sparks of will For all of us waiting, your kingdom will come`	[reply] [d/l] [select]

Show us what you want to achieve. Something like this: `use warnings; use strict; use Data::Dumper; my %hoh; while (<DATA>) { my @items = split ' '; push @{$hoh{'this'}->{'that'}->{'theOther'} }, [@items]; } print Dumper (\%hoh); __DATA__ eggs bacon cheese tomatoes potatoes onions beans peas cabbage` [download] Read more...

How do i maintain uniqueness for "$testcase" in the hash while generating this hash That's obvious: you need to convolve the contraint of the unique foreign key index parameter; preferably using a FFT, or failing that, using a 15mm to 1/2" compression adaptor. Alternately, you might want to reformulate your question in such a way that someone other than you has a clue what you're asking... Dave.	[reply]

Show us some code that runs (and doesn't depend on anything external to the code), the output that you see, and the output that you expect. We have seen this bacon and eggs example before and it has just as many unknowns as it did the first time around. We can invent stories, but sometimes our mind reading ability fails. Code speaks louder than words. Perl is Huffman encoded by design.	[reply]
