Re^2: Passing Regex Pattern in Subroutine

Yes, this is what I am looking for. But I don't understand why you had to use 'map' to pass the regular expression.

Is it because when you run get_data( map { "^$_" @ids } ), it is like doing get_data( "^john" ) and that is being passed to the subroutine?

Is it because when you run get_data( map { "^$_" @ids } ), it is like doing get_data( "^john" ) and that is being passed to the subroutine? Not exactly. The map is like doing: `get_data( '^john' , '^james' );` [download]	[reply] [d/l]
