Re^2: Can't get Dialog or messageBox to work from button

Sure!

sub xx { shift() + 1 }
say \&xx(3);                        # SCALAR(0x60003b660)
say ${ \&xx(3) };                   # 4
say sub { \&xx(shift) }->(3);       # SCALAR(0x60003b888)
say ${ sub { \&xx(shift) }->(3) };  # 4

How much easier than

say xx(3);                   # 4
say sub { xx(shift) }->(3);  # 4

I don't use Tk and therefore i didn't really read the friendly manual but i would like to mention that i figured out in a hurry that the construct hotchiwawa mentions can be found here and here. Perhaps he jumped to the wrong conclusion? Best regards, Karl ŤThe Crux of the Biscuit is the Apostropheť	[reply]

I don't use Tk and therefore i didn't really read the friendly manual This is not Tk related. This is referencing in Perl. that the construct hotchiwawa mentions can be found here and here No, it can't. There's a big difference between the two: `my $value_ref = \&callback(); my $code_ref = \&callback; # <-- See? No parentheses!` [download] ($q=q:Sq=~/;[c](.)(.)/;chr(-\|\|-\|5+lengthSq)`"S\|oS2"`map{chr \|+ord }map{substrSq`S_+\|`\|}3E\|-\|`7**2-3:)=~y+S\|`+$1,++print+eval$q,q,a, [download]	[reply] [d/l] [select]
