Re^2: An Array without an Index

The my in the while loop creates a new @row variable each time through the loop. This is almost certainly not what you wanted.

Actually it most certainly is -- the @row=(); is what is an error -- probably because OP isn't using strict and warnings

He said the program runs under strict and warnings. But the `@row = ()` and the `my @row` in the `while` loop are two distinct variables. Since he is not using the first `@row`, it does not seem to be the cause of his problems. CountZero A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James My blog: Imperial Deltronics	[reply] [d/l] [select]

He said the program runs under strict and warnings ... it does not seem to be the cause of his problems. Of course, this is just a symptom ( not coping with scoping ) ; the cause is indeterminable.	[reply]
