Regular Expression

[Lars Nilsson]

I need to check that the user as put in at least one character between
a-z upper or lowercase in a name field. They can put in whatever they
like but there as to be a character a-z in the string. How shall the
test expression look like?

/Lars

You mean:

/[a-zA-Z/

That's what I get for staying up all night. Should be (of course)

/[a-zA-Z]/

my $alpha_count = $name =~ tr/a-zA-Z//;
if ( $alpha_count >= 1 ) {

But if you really want to use a regular expression instead:

my $alpha_count = () = $name =~ /[a-zA-Z]/g;
if ( $alpha_count >= 1 ) {
