Need Help??

The syntax for 'join' is:

join EXPR,LIST

So your code should be

$variable = join("\n",@variable = <INFILE>);

Just a small note: Using slurp mode is usually far more efficient than `join()`ing a temporary array or list. `$variable=do { local $/=undef; <INFILE> };` Alexander -- Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)	[reply] [d/l] [select]

Although the questioner probably does not want to be using `join` here at all - reading the file via `<INFILE>` does not remove the file's newlines, so there is probably no need to be adding more.	[reply] [d/l] [select]
