Coordinate problem
There is a phenomenon where coordinates disappear. In what cases do coordinates disappear? The operation is normal, but the coordinates disappear.
why do you have "return" 2 places in your program. Return only works when you have called a program. I would start with removing those and I believe it should not remove the values.
Chris Annin I'm using the return statement as if it were the end of a program. I've written down two types of return to the origin. Let's delete them.
Please try updating to the latest version 6.6 and make sure to watch the basic programming tutorial on the tutorials page. I have now eliminated the need for a return function. The program template as a "run once" section and a "program loop" section. Called programs will automatically return to the main program.
