Hi, I have programmed 10 Picaxe 08M2Xs with PE6, all with the same program. When I went back to solve a problem I noticed that part of the program was highlighted in red, with a flag symbol to the left. In looking this up, I think that called a "breakpoint". I don't know what that is; my main concern is that it may affect the way the program runs. I don't know how it got there, and I don't know whether it was there when I programmed the units. It will take some time to disassemble all of the component boxes, move the jumper over to "program", load the program again, and then patch it all together again. I am hoping the breakpoint won't affect the way the program runs, so that I can ignore this. Can someone help with the answer? Thanks!
