Cannot delete this variable because it is used in macro Main by icon Loop

[andeug]

Hi,


I have a little project I am working on, and I realized I cannot delete the variable marked in the picture below if I am choosing "Loop Forever":

I can rename it, but in my FC project, I cannot see it anywhere on a first view.
So I started to dig and found it on Properties: Loop, hidden on "Loop until", which was not selected.

Is this a bug that should be reported to Matrix TSL, or is this how FC is expected to work? Below is the project example.

Thanks for the report. As a convenience, Flowcode remembers any expression used in a Loop command. But this is hidden when "Loop Forever" is selected.

This should be fairly easy to fix - I will allow the variable to be deleted if it only shows in hidden/remembered expressions.

While waiting for a fix, the variable can be removed using your favorite text editor.
Before making any changes, always make a backup of the original first, as it's easy to make a mistake that will prevent your project from loading.

I have actually fixed the issue within the same project, after digging a bit into Loop.
I have only seen this problem once, so it does not affect me (but might affect other newbies like me).

No problem.
For anyone else, if you do face the same issue and don't want to edit the fcfx file within an editor.
Just Right-click on the variable and select List occurrences.
Double click (or right-click and select Show) in the loop icon that appears within Icon Lists window.
You might need to change the loop type to Count, as that is only time you will find a variable.
You find the variable causing the issue (until and update hase fixed it of course).
