Well, I think a regex is your best bet.
---
$data = 'This is a very long string ';
$data =~ s/\s+$//;
---
That will trim all trailing spaces.
Without a regex you could try something like
---
$data = 'This is a very long string ';
do {
$_ = $data;
$test = chop;
chop $data unless $test ne " ";
} until ($test ne " ");
---
But I still think the regex is the best way

Subject: removing spaces from the end of a string WITHOUT a REGEX
Hi all,
I have a string I want to remove spaces from but without the use of a
regex.
e.g. 'This is a very long string ', I want to store as 'This is a very
long string'
Notice the removal of 4 spaces at the end. The number of spaces at the
end is variable. If I have to use a regex I will, but there is always
another way of skinning the cat in perl.
Cheers for now.
Hamish
