Hi there,
how do i pass arguments with spaces in it.
exaple if i pass fun("abc is not bcd");
@ARGV would store this as 4 words. how do i retrieve it as $var = "abc is
not bcd";

indicates that you pass the string to a _subroutine_

| @ARGV |
is normally used to get arguments to the _script_

Could you provide some code, and how you invoke it?
joe
lets assume I call the function as show below
func("arg1","arg2","this is arg 3", "this is arg 4");
now inside func function how do I retrieve my arguments
sub func()
{
foreach $arg in (@ARGV) {
print "$argn";
}
}
this would print
arg1
arg2
this
is
arg3
this
is
arg4

use @ARGV for passing args from commandline. You should use @_ for
function, try this:
func("arg1","arg2","this is arg 3", "this is arg 4");
sub func {
foreach my $arg (@_) {
print "$argn";
}
}

sub func() {
# arguments are in @_, not @ARGV
print join "-", @_;
}
Invocations:
func("arg1", "arg2");
# prints:
arg1-arg2
func("a string with blanks", "another one");
# prints:
a string with blanks-another one
You should at least read
perldoc perlsub
