Hello. I am working currently on a project, which opens specific channels on specific a modem.
I have wrapped a modem to modem1, modem2, modem3, modem4, modem5, and modem6. How can I connect the string "modem" to a variable that holds the number that I want to add to the end of string? The code looks something like this:


for z=1,6 do
  "modem"..z.open(x) --Help me with this line
end

In this case I am trying to open the channel x on each modem.

That is not how variables work.

I suggest you use a table.

Bulding a little on KoGY's answer:

Variables and strings are two different things. When you enclose something in quotes it becomes a string. A variable can hold (or in CC's case, point to) a string, but a string is just a string.

Depending on what version of CC you're using, you could do something like this…


local modem = { peripheral.find("modem") } --# capture all found modems in a table call 'modem'
local x = 2345
for i = 1, #modem do --# start a loop that will count through the number of modems
  modem[i].open(x) --# open channel 'x' on each modem (e.g. modem[1], modem[2], etc.)
end
