Re^2: Performing search and replace on an output file prior to printing

Can you clarify "removed useless slice"? I know this is not a golf problem, but one liners are a place where brevity can be useful. As I see it:

@v = ("w", @F[2,3], length($F[9]))

is valid syntax and would save 5 characters.

But God demonstrates His own love toward us, in that while we were yet sinners, Christ died for us. Romans 5:8 (NASB)

I started with `@v{1,3} = (...)` and a separate computation of `$v[0]` and `$v[2]`. But I turned that into `@v{0,1,2,3} = (...)`, where the slice on @v is not only useless, but also incorrect now that I think of it (since it was actually a slice on %v). And yes the code can be shorter (there is a lot of unnecessary white space for example), but I was expecting TJCooper to adapt the oneliner to his needs anyway.	[reply] [d/l] [select]
