Re^3: sub will not return data (after data has been returned) by jeffa (Bishop) on Jun 18, 2015 at 00:33 UTC
You can also call the function 4 times instead: `my @test_1_data = test_1($test); my @test_2_data; push @test_2_data, test_1( $test ) for 1 .. 4;` [download] Notice that `test_2()` is not even called. A for loop around the first sub accomplishes the same goal. jeffa L-LL-L--L-LL-L--L-LL-L-- -R--R-RR-R--R-RR-R--R-RR B--B--B--B--B--B--B--B-- H---H---H---H---H---H--- (the triplet paradiddle with high-hat)	[reply] [d/l]

thats wild that it doesnt even need test_2() called. I tried it and it did work, but why does it work even when test_2() isnt called? I will more than likely use this, otherwise I will have to change up abunch of code. EDIT: i found another problem as well ;) I also am converting the data to its hex equivalent with unpack('H', ()). Why does this fail: `push @test_2_data, unpack('H', (test_2( $test ))) for 1 .. 4; print $_ for(@test_2_data);` [download] And this works: `push @test_2_data, test_2( $test ) for 1 .. 4; for(@test_2_data){ $_ = unpack('H*', $_); } print $_ for(@test_2_data);` [download]	[reply] [d/l] [select]
