Thank you all.. Now i'm able to open files from other drives and directories.. The EXPR in glob EXPR is actually a kind of regexp then? What is this new q{} operator?I am sorry for the previous dubious emails, they actually were errors made by the mail sender.
No, it's not a regex. It's just an expression. EXPR is just short for "expression". In the documentation it translates roughly to "the type of input this operator or function accepts." You then need to read the rest of the doc see what kind of input a particular operator or function accepts. the type of expression that satisfies "glob EXPR" is very different from one that would satisfy "unless EXPR," for instance. In glob's case, the expression is a combination of literal characters and wildcards that mimic the wildcard syntax of unix shell(s) (actually BSD glob). It's a glob expression, and it's very different from from a perl regex (or any other regex). You can read all about q//, qq//, qw//, and their friends in perlop under "Quote and Quote-like Operators." Better yet, just pick up a copy of _Learning Perl_ or _Learning Perl for Win32_ from your local bookstore. The q*// operators are common ways of quoting text, and you'll want to get familiat with them.
