Bill, I think we're talking about two different things.

try putting an if statem to test for digits.

Does anybody know whether there is some equivalent in Perl to VB's
IsObject function?
It would be helpful to have a description of the VB IsObject function, but
judging by the name, you could do something like this (untested)
sub isObject {
my %types = map {$_=$_} qw(SCALAR ARRAY
It depends on what you're trying to do, but I think the ref function might work. It
returns a true value if the argument is a reference. The value it returns just so
happens to be the type of reference (i.e. ARRAY, CODE, HASH, etc). Also, if the
reference has been blessed into a package it

See ref() -- perldoc -f ref()
i.e.:
use IO::File;
sub print_type {
my $arg = shift;
print Argument is: . ref($arg) . \n;
}
my $object = IO::File-new();
See ref() -- perldoc -f ref()
While ref is useful, you do have to be careful in this particular situation
to avoid the non-OO references CODE, HASH, ARRAY, and SCALAR. Someone else
already posted a solution, I believe.
This might also work (although it will cause a scan of the entire
I assume IsObject is a method that returns TRUE if the given object is of
the given class, and FALSE otherwise. If this is the case, the 'canonical'
way to do it is to use UNIVERSAL::isa. See the 'perlobj' documentation for
details. Here's some (working, this time!) sample code:
