Strange behaviour in substitution 2

[audiopro]

I am using this substitution to clean some inputted data.
I have used the same code numerous times before without problems.

$FieldValue = "Charlie----";
print "FVB - $FieldValue<br>";
$FieldValue = ~s/[^a-zA-Z0-9 \@\.]//gi;
print "FVA - $FieldValue<br><br>";

Gives output of:-

FVB - Charlie----
FVA - 18446744073709551615

Why is it substituting the string for a number?

Hi

Unary [tt]"~"[/tt] performs bitwise negation, that is, 1's complement.

( man perlop | Symbolic Unary Operators )

Use the [tt]=~[/tt] operator instead :

[navy]$FieldValue[/navy] [teal]=~[/teal] [b]s[/b][fuchsia]/[^a-zA-Z0-9 \@\.]//[/fuchsia][b]gi[/b][teal];[/teal]

Suppress the space between [tt]=[/tt] and [tt]~[/tt] (and the [tt]i[/tt] modifier seems not useful)

I have been using that operator for years and never knew that.
All is working now - it is the simple things that catch me out.
Thanks
