When using fs.open("filename", "a") do you start writing at the end of the file? I am creating an e-mail server and this is my code so far...

Spoiler

function escape()
term.clear()
term.setCursorPos(1,1)
print("MENU:")
print("1.   Send")
print("2.   Discard & Quit")
print("3.   Back")
print("Press 1, 2, or 3)
local event, esc = os.pullEvent("char")
if esc == 1 then
type = 2
send()
elseif esc == 2 then
type = 2
elseif esc == 3 then
type = 1
erm.clear()
term.setCursorPos(1,1)
print("Please Type Body")
print("To Exit Push Escape")
print(read.readAll())
read.close()
else
print("wrong key")
type = 1
term.clear()
term.setCursorPos(1,1)
print("Please Type Body")
print("To Exit Push Escape")
print(read.readAll())
read.close()
end
end
print("Please Type Body")
print("To Exit push Escape")
local read = fs.open("body". "r")
local append = fs.open("body", "a")
local write = fs.open("body", "w")
term.setCursorBlink(true)
local event, key = os.pullEvent("char")
if key == "escape" then
escape()
else
write.write(key)
write(key)
type = 1
if type == 1 then
local event, key = os.pullEvent("char")
if key == "escape" then
escape()
else
append.write(key)
write(key)
end
end

From the wiki:

Quote

"a" to open for writing but keep existing data and append any writes to the end of the file

Is it so hard to go to the wiki and read a little?

[tfoote]

I went there... But it didn't say weather it wrote to annother line. That is my problem. I want to know if it continues where it left of or starts a new line

[MysticT]

It writes to the end of the file, so if there was a newline character at the end it will start in the next line, otherwise it keeps writing in the same line.

Thank you

Try:

file.writeLine(message)

Also, the newline character is "n".
