Hi sir Nobu (aka nobu.nokada@softhome.net

You wrote:

Do you want to write like as:
Fp(“input.txt”, 4) {|line| p line}
?

def Fp (file,skip)
File.open(file) do |f|
skip.times {f.readline}
f.each { |line| p line }
f.each { |line| yield line }
end
end

This is neat. Very Ruby, imho.

Or

def Fp(file, skip, &block)
File.open(file) do |f|
skip.times {f.readline}
f.each(&block)
end
end

this looks like what I did… it also looks like the above… see:

def Fp2 (file, skip, &procarg)
File.open(file) do |f|
skip.times {f.readline}
f.each {|line| procarg.call(line)}
end
end

Anyway, it looks “dirty” maybe because of &/call… I need more practice :slight_smile:

Many thanks again.
