If in a subroutine, I have a statements
sub
{
my $local_var=1
....
$local_var=$local_var+1;
....
}
then the next time I run this subroutine, $local_var is reinitialized to
1. However, I would like to have it retain its value from the previous
call to the subroutine. For example, if $local_var is 5 at the end of
the subroutine call, then it would have this initial value the next time
the subroutine is called. This can be done by making $local_var a global
variable which I do not want to do. Is there a way to achieve what I am
trying to do and still retain $local_var as a local variable, sort of
what is called a static variable in C, I think?
Thanks,
Dick Fell
