How to clear the contents of Memo completely?

天涯沦落人

How can the content in Memo be completely cleared, that is to say, the content of the last run will no longer be displayed in the next run.
I made a display box, but after clearing each time, I run another file again, and there are still some contents displayed in the last run, such as the first run:
0 CONST A ADR = 1 LEVEL = 0 SIZE = 6
1 VAR A ADR = 3 LEVEL = 0 SIZE = 0
2 VAR B ADR = 4 LEVEL = 0 SIZE = 0
3 VAR C ADR = 5 LEVEL = 0 SIZE = 0

When running another file for the second time after clearing, it is displayed as follows:
0 CONST D ADR = 1 LEVEL = 0 SIZE = 4
1 VAR D ADR = 3 LEVEL = 0 SIZE = 0
2 VAR B ADR = 4 LEVEL = 0 SIZE = 0
3 VAR C ADR = 5 LEVEL = 0 SIZE = 0
But among them
2 VAR B ADR = 4 LEVEL = 0 SIZE = 0
3 VAR C ADR = 5 LEVEL = 0 SIZE = 0
Two are missing from the second file,
I want to know how to clear it up? Is it clearing the cache? If so, what should I do? Thank you!

Memo-> Clear (); can't be completely cleared, there are still two after running

Should be a problem with your code
Memo1-> Clear () should be deleted

It is not a problem of Clear ();

baiyunyy

Memo1-> lines-> Clear ()

Clear() was originally used for clearing. Clearing is not your code problem. I don't believe in trying to create a new project.

clear() can definitely be emptied, you can see step by step

Memo1->Clear();//Clear
  memo->items->Add(...)//Add
memo->clear() or memo->items->clear()
  I haven't used it for a long time, I forgot
