RedPhonebook

Hello. This is a phonebook program that you can enter the IDs of computers and it will save them.

Download: [attachment=198:RedPhonebook.txt]

pleae put in to normal code im nooob

You should add pictures to see it in action. Also, I'm not a downloader, and source code in threads that doesn't require downloads is my thing.

Some slight improvements:

• Selecting the 'delete' entry would have always resulted in deletion of the entries.
• Sufficient use of the program would have eventually overflowed the function stack.
• shell.run() is bad.
• tabulateCommon() is good.

term.setCursorPos(1, 5)
textutils.slowPrint("Initializing RedPhonebook...")
tEntries = {}
if fs.exists("//.phonebook.cfg") then
local file = io.open("//.phonebook.cfg", "r")
local sLine = file:read()
while sLine do
  table.insert(tEntries, sLine)
  sLine = file:read()
end
file:close()
else
textutils.slowPrint("Config file not found. Creating file.")
table.insert(tEntries, "")

A table? How do tables work anyways? I think I want to use one as an inventory.

From a simple google search: Tables tutorial

any way this could be hooked into Nitrogen Fingers email client. I'd love to be able to enter a persons name instead of Computer ID to email them.
