Deleting unused labels is not always valid #1

Consider

If A
Lbl B
Disp "C

If Lbl B is blindly deleted, then the program will look like this:

If A
Disp "C

In this program, Disp "C will not run if A is false. Currently, tibo is very happy to delete Lbl B.

@rpitasky, hello! How are you? I understand the problem you described and the potential issues that can arise:

Conditional Execution: The output will only occur if a specific condition is true. Loss of Control Flow: Removing the label could disrupt the intended flow of the program. Potential Bugs: Blindly deleting the line might introduce unforeseen bugs.

Could you explain a bit more about how to fix this bug?
