This is a follow-up on a post ( Using extensions in modules ) when I thought there is a bug in the module system. The point is that a module should be self-contained. So, if it relies on some extensions, it should decl… --- ## [Background color of widgets](https://forum.netlogo.org/t/background-color-of-widgets/859)

Sometimes I want to write generic sub-procedures or functions so they can be called both before and after the “reset-ticks” command. Some of these might use “ticks” but this causes an error if used before reset-ticks. C… --- ## [A primitive for assertions](https://forum.netlogo.org/t/a-primitive-for-assertions/803)
