Scalable List
#1
An example for the Discord channel.  This isn't set up with a very intuitive interface, as I cobbled it together in all of about 10 minutes quick work.  I doubt anyone will learn anything from this, without popping into discord and actually chatting with me in person so I can help walk through what we're doing and why in a life-time session.  It's just easier to share code of this length here, than it is there, but it's easier there to actually discuss it in real time so I can answer questions and such as we go.  My apologies to anyone who finds this confusing or a waste of time.  ;D 


Code: (Select All)
Screen _NewImage(640, 640, 32)
$Color:32

ReDim Shared lists(5, 5, 0) As String * 10 'make a resizable list array
Dim Shared As Integer list2use, listcount 'track which list we're using, and how many we have

"Return Home" = 11 characters...
it is better  REDIM lists(5,5,0) as  string  * 11, isn't it?

Hi Steve
I was  just kidding....

Do you can post an help for user?
I never got a list in a box, I can click on a box and get the right position box as feedback, I never was able to enter Edit mode

What must I expect from it?

It probably would have just been better to call it a plain "Home" button, but it's still functional even if it's leaving an E dangling.  Wink
