You need to add parenthesise after the function name, like so:
function start() -- <== see the brackets.
echo("buddy 0.1 made by 6d23")
end
start() -- <== You need to call the function aswell
These are where you can put variables, to be processed by the function. For example:
function add(a,b) -- <== seperated by commas
return a+b -- <== "return" makes the function send back whatever you set it to return
end
Test = add(4,5) -- <== As we made the function return a+b, this will set "Test" to 9
echo(Test) -- <== Quick Test
The bits in green are comments and don't need to be removed if you don't want.
