my idea of "repeat" was that the re-occurence of a character in ADDITION to the original character..i see your point there though.... i will add some adjustment to the help menu to carlify this..
I am not a native english speaker and my english is so-so... I can misunderstand a lot of things

.i can modify the program to neglect the IOError messages after successfully finding the pass and the piping stopped...are you willing to test for me? if yes...send me a private message..i will send a modified program so that you can test for IOError solution!
For sure!
I will send you a MP.
