you may need to reset $/ to read your data, and then use hash keys to
sort your results. see the following code.
-----------------------------------------------------------------------
#!/usr/bin/perl -w
use strict;
my %h=();
my $n;
{
local $/="Title";
while(<DATA>) {
chomp;
$h{$1}=$2 if(/\A\d+=(.*?)\n(.*)\z/sm);
}
}
foreach my $k(sort{lc $a cmp lc $b} keys %h) {
$n++;
print "Title$n=$k\n$h{$k}";
}
__DATA__
Title1=B2a
Command1=c:\chi\cw.exe
Title2=f2a
Directory1=c:\chi
Type1=1
Command2=c:\chi\cw.exe
Directory2=c:\chi
Options2=%@%
Type11=2
Title14=Ma3
Command14=c:\chi\cpb.bat
Options14=c:\temp\temp.bin
Use long names3=1
Title12=Dir
Command12=Tfd
Title13=a2h
Command13=c:\bat\a2h.bat
options13=%@dpn%
Show13=2
Command31=C:\bat\tview.bat
Use long names31=1
Title31=tview
