Jonathan, Thanks for the reply..
>use strict; >Always, always, declare your variables with my.[1] What do you mean by "function" variables? Ok, I understand you mean use 'my' to declare containers for incoming arg variables - what about variables used just within the function - ought they be 'my' vars as well? Does this apply to the main function/main program body too, or is this overkill? >If you are suggesting "pass by global variable" then dont! It can by very hard to debug these programs. What do you mean 'pass by global variable'? Pass the global var in as the arg and work on the same global variable within the function? Thanks! Mark p.s. what does 'shift' refer to - apart from a list operator? -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
