Re^2: Tkx scrolling

Thanks for your answer.

I have since found that

$canvas4->yview('moveto', (.09));  # where a fraction 0 to 1 is used t
+o position the cursor
[download]

works nicely to do what I want.

I write in linux but the sailing club I write for uses ms windows so I compile it in XP in Virtualbox where the version of Perl requires &subname()

Also for my $i(0..100) {$results[$i] = 2*$i;} is not in the original code. That was just to use in the small demo.

"... ms windows ... XP in Virtualbox where the version of Perl requires &subname()" I don't see how WinXP has any bearing on this. I have a very old laptop, that I probably only use a couple of times a year: it runs WinXP and has Perl installed. I've never had any reason to use '`&subname()`' for any Perl code on that machine. I don't see the relevance of mentioning VirtualBox. I've certainly run Perl code under VirtualBox/WinXP for cross-platform testing purposes in the past: again, I've never had any reason to use '`&subname()`'. What version of Perl are you running that you think requires '`&subname()`'? If you run the following, do you get the the same result that I show? `$ perl -le 'sub test { 42 } print test(); print &test()' 42 42` [download] — Ken	[reply] [d/l] [select]
