Nope he is correct, it was a problem with 'and' having lower precedence than ',' `grep ( ( expression) and ( expression) and ( expression ) , @files )` [download] Is interpreted as `grep ( ( expression) and ( expression) and ( ( expression ) , @files ) + )` [download] According to `perldoc -f grep`, the construct `grep( expression, list )` is allowed. But it is indeed confusing to man and machine!. Have Fun	[reply] [d/l] [select]

The post to which I replied said `... and ( expression , @files )`, not `... and ( expression ) , @files` as you used, so my reply does apply to the post to which I replied.	[reply] [d/l] [select]
