Yes, much more beautiful! sadly I still got to use perl 5.10 so `local *HTEC...` is not working However, the `\|\|= 0` version makes the code much more better and makes me get rid of all the if statements! I will use it that way! Thanks a lot! Cheers! Tobias	[reply] [d/l] [select]

sadly I still got to use perl 5.10 so local HTEC... is not working* Sure it is, it worked since the very first perl5, at least `perl -MData::Dump -e" dd $f={2,{4,{6,8}}}; local *H=$$f{2}{4}; dd\%H" { 2 => { 4 => { 6 => 8 } } } { 6 => 8 }` [download]	[reply] [d/l]

Hey, you are right! :-) Perfect! But there is one thing, I have to remove the `use strict;` else I get a: `Global symbol "%HTEC" requires explicit package name at...` Thanks a lot! Tobias	[reply] [d/l] [select]

Bah, start short too :) `$HTEC{$5} = { 'Start' => $1, 'End' => $2, 'Size' => $3, 'Symbol' => $4, 'Memory' => $6, 'OutputSection' => $7, 'InputSection' => $8, 'InputObject' => $9, };` [download]	[reply] [d/l]

and while you're at it, drop the single quotes for barewords :) $HTEC{perl}{is}{Perl}	[reply]
