functions
Post by Alincon on Sep 4th, 2016, 02:29am

I had some trouble with a function that had no parameters.
(it uses global variables)
It worked when I added a dummy parameter.
Are functions in LBB required to have at least one parameter passed?
I think subs do not require any parameters to be passed.

It works for me:

Code:
    global MyGlobal
    MyGlobal = 12345
    print noparms()
    end

function noparms()
    noparms = MyGlobal
end function

If you want to report a problem, it would be enormously helpful if you could include a self-contained program that demonstrates it. Simply saying "I had some trouble" doesn't really cut it!

I keep forgetting to include a code sample, even though I know better. Sorry.
But I see your sample shows an empty set of parens.
I didn't have them in my code. That must be where I went wrong.

I can't see how it would distinguish a function call from a regular variable without them. A variable is allowed to have the same name as a function in LB, isn't it?
