Hi All, I am using code written by some one else. I didn't understand the difference between these subroutines, the way they were defined.
1. sub addToLog { Some code } Any specific reason where we should not use braces ?? 2. sub displayEnv( ) { " } Any specific reason why we should use braces ?? 3. sub trim($) { " } Any specific reason why we should use a brace with a $ sign in it ?? Could some one specify reason when to use braces and when not to use . Replies are highly appreciated and thanks in advance for your help. Regards Anand
