 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Well now I remember (RTFM) that it's either DO WHILE:LOOP or DO:LOOP UNTIL but of course I forgot and was scratching my head for a bit. Would it be a good idea to have the interpreter pick-up on this and flag an error message? My DO UNTIL Pin(22) = 0 : LOOP Just sat there looping away.  Board: E100 MM.VER:5.0501 |

BTW. DO WHILE:LOOP or DO:LOOP UNTIL are explained in the manual. But this also works: Do:Loop While Inkey$<>Chr$(ENTER) Michael causality ≠ correlation ≠ coincidence |

Maybe . . . DO WHILE(PIN(22) = 0) . . . . . . LOOP |

Oh sure but that would need to be PIN(22) = 1 I used the other option: DO . . LOOP UNTIL PIN(22) = 0 |

This is one of the problems with working in the small memory space of a microcontroller. There are many, many ways of incorrectly constructing a command and it is impossible to trap them all and still fit in the given flash memory space. Already error checking takes up a lot of space (I guess about 20%) and that is only trapping the obvious errors. Compilers like C and C++ have the advantage here because they are running on a desktop computer with almost unlimited memory. But then they have other disadvantages as well.
