Write in *.txt file from variables values , with separate new lines.

[Peter58]

I can read my file, but cannot write in it, with every value per line... >>> 
Thanks to your help...

import strutils

let cont = readFile("values.txt")

let val = cont.splitLines()

echo val

# result >> (OK)

# 1111

# 2222

# 3333

echo "val1: ", val[0], " val2: ", val[1], " val3: ", val[2]

# result >> @["1111", "2222", "3333"] (OK)

var val1 = readLine(stdin) # I put 5555

var val2 = readLine(stdin) # I put 6666

var val3 = readLine(stdin) # I put 7777

var contW = open("values.txt", fmWrite)

contW.writeLine(new1, new2, new3) # Don't work ! ! !

# result > 55556666777 , instead of one per line, i want ! ...

contW.close()
