I've tried different things but nothing worked. How do I make a program create another program?
Like:

fs.open("test", w)
code to write the program
fs.close

[Lyqyd]

local handle = io.open("outfile", "w")
if handle then
  handle:write([[
print("Hello, World!")
]])
  handle:close()
end

EDIT: Damn ninjas.

You can use this simple piece of code:

local f  = io.open("test", "w")

f:write([[
	-- program code here
	print("Hello from test!")
]])

f:close()

Could you also put comments in the code so it is easier to understand?

EDIT: nvm, I figured it out. Thanks for the quick help

Yeah

local handle = io.open("outfile", "w")
if handle then
    handle:write(
[[
-- Declare a function
local function foo( s )
    print( s )
end

foo( "Hello!" )
]])
    handle:close()
end

[Finnvos123]

local f = fs.open("startup", w)
f:write([[
	print"Starting...."
	sleep(1)
]])
f:close()

With this code I get:
test:1: Expected string, string

Put quotes around w.

[Finnvos123]

Somehow the program/file it creates is completely empty.
After some testing I found out that it doesn't do anything to the file.

Hmmm...if your full code is the above with just the "w" replacement. It really should work...

Have you tried restarting the PC? Lol typical IT solution. Might you have edited io somehow.

Try fs?

local f = fs.open("startup","w")
w.write([[print"Starting...."
sleep(1)]]
)
w.close()

Really the same thing...
Have you changed any ComputerCraft files?

[Finnvos123]

And by restarting it suddenly worked.
HOW!?

[remiX]

Haha. You probably overwrote something sometime...
