The ?{} construct evaluates perl code inside a regular expression. By default it's off, so you want to do use re 'eval' to turn it on.

To clarify, (?{}) constructs can be used without the `use re 'eval'` pragma, but only if the regex contains no elements interpolated from variables. Perhaps an example is called for: `#fine /a (.) a(.)(?{push @substrings, $^N}) (?!)/ #not fine: we get part of the regex body from a variable /$regex(?{push @substrings, $^N}) (?!)/ ^^^^^^ this variable interpolation requires that you use re 'eval'` [download] Type `perldoc re` at your command prompt for more info. Code is (almost) always untested. http://www.justicepoetic.net/	[reply] [d/l] [select]

Thanks for the replies:)I checked the perldoc re and and it solved the eval problem but still although there is correct number of match in the array they are all undefined. I would appreciate any help? thanks	[reply]
