I can't tell from here. Please post your current code and exactly what you did with it.

also can a pointer to a file ever be the value 0
No. Then you wouldn't be able to tell it apart from NULL.

and can a pid value ever be 0?
No.

So, can anybody tell me what is wrong about
this program?... (2 Replies)

ppi::token::quotelike
PPI::Token::QuoteLike(3) User Contributed Perl Documentation PPI::Token::QuoteLike(3)
NAME
PPI::Token::QuoteLike - Quote-like operator abstract base class
INHERITANCE
PPI::Token::QuoteLike
isa PPI::Token
isa PPI::Element
DESCRIPTION
The "PPI::Token::QuoteLike" class is never instantiated, and simply provides a common abstract base class for the five quote-like operator
classes. In PPI, a "quote-like" is the set of quote-like things that exclude the string quotes and regular expressions.
The subclasses of "PPI::Token::QuoteLike" are:
qw{} - PPI::Token::QuoteLike::Words
`` - PPI::Token::QuoteLike::Backtick
qx{} - PPI::Token::QuoteLike::Command
qr// - PPI::Token::QuoteLike::Regexp
<FOO> - PPI::Token::QuoteLike::Readline
The names are hopefully obvious enough not to have to explain what each class is. See their pages for more details.
You may note that the backtick and command quote-like are treated separately, even though they do the same thing. This is intentional, as
the inherit from and are processed by two different parts of the PPI's quote engine.
